I think this post went way over people’s heads 😆 (not trying to build a hellkitten here) just simply asked what gains has someone PERSONALLY Noted from a tune and pcm install in a 19 3.6l v6.. not supercharger, not cammed not spraying!! Just a 1k dollar tune and pcm unlock in a similar built…

It would appear that the answers you got from us have actually gone over your head. You came here for knowledgeable advice, and it's clear you didn't get the answer you wanted.

About all a tune does is bump up the timing, which usually creates destructive pre-ignition. Even a custom tune will only get you to the levels that the stock V6-AWD Charger Pursuit comes with. A Pursuit ECM would not work in your case, because the '19 Pursuit model still used the A580 5-spd auto (incompatible with the 845RE in yours), and the 2021+ models are the 850RE and AWD only (also incompatible with your '19).

Anything that would help noticeably, without voiding the warranty and/or reliability of the car, will cost well over $1000 just in parts. Assuming the parts would be available, not counting labor necessary for most of the larger jobs.

That's really all there is to it. You can get the torch and welder out, and turn it into the Batmobile, but with virtually any newer car, the idea of just bolting on parts-store junk to wake it up a little bit is simply not possible.

We deal with these questions very frequently (and we're used to our replies being dismissed, followed - after some time - by questions from the OP's of how to rectify their hack jobs).
The engineers have these cars optimized for the best street performance they can get away with under the law. That's a simple fact.
The best thing to do, again, is to simply leave it alone and drive it.

That offers zero advantage from the stock intake. In fact, it might even scoop water if you encounter a large puddle or flooding, which could hydrolock the engine.

well it is what it is then. just Can’t believe this grey area of these 300s will forever be this hard to figured out or is impossible to figure out. And understand I’m just speaking from logic.. a grand I can spend but until I find someone who can tune it and I can have proof on paper of gains well never know..(for now)

It’s keeping hot air out basically as much as the stock filter just with an aftermarket CAI ..I will say tho it has improved engine and coolant temp ever since I did the install, even in high traffic(I live in Houston) my coolant temp don’t run as hot as it use to... but back to the original convo I get it there is “nothing” I can do to make any gains on this car.. and I have multiple vehicles so I don’t take it out when we are expecting hard rain not including the mesh I put on the entrance of the air duck if I do run into debris or slight rain..

Here's the big problem - a lot of the tuner shops have gotten fined recently for performing modifications that defeated or eliminated emission controls. Far fewer places will probably be in the tuning business going forward.
Since there are fewer people tuning a Chrysler 300, look for reviews from V6 Charger and Challenger owners of the options you want to follow. If it works for those cars, it will work for yours. But be aware. If it were me I'd want to see dyno or timeslips to back it up. I've never met anyone that doesn't brag about how much their modifications helped according the unscientific "butt dyno".

I understand what you are saying, but the V6 cars are not tunable cars. There is no tuning that can be done. They are as optimal as they can be within the bounds of state and federal fuel economy and emissions requirements. Modifying the intake & exhaust to remove (what you believe to be) restrictions will hurt your performance.

As others have said, lots of common mods (such as a "cold air intake") are actually detrimental to the car's performance and function.

see I can understand that. If it just can’t be done because of certain buildings standards Chrysler did then ok I totally get it but it’s still just unreal 😆 that you can do absolutely nothing to an engine (besides superchargers,nos cams ect) to make it push a few more horses and torq 😞 I had a 95 Chevy single cab v6 back in like 2011 and I moded tha fugg out that lil 4.3 v6 engine it already had a little done to it, I just took it further lol it had better injectors/ headers/ full exhaust/ CAI/ I changed the rear differential/ tuned it/ ran electrical fans/ performance spark plugs I did a lot to it that 4.3 would squeal 2gear and on a good day the 3rd would give a lil squeak I had buddies who would experiment on their chevys so parts were easy to come by but maaan when I tell you I was taking the 350s and 454 chevy trucks easy they had no chance I would slowly pull on the mustangs 00-10GTs both models. that truck would push like 135/140 from what I was told The speedometer stopped at 100 and eventually broke 😂 .. so I’m just in disbelief I guess...and for that Chevrolet the engine eventually went bye bye and started slapping hard as fu😆

The difference between 1995 and now is that the computing power has grown exponentially for manufacturers to use during development and while the engine is running, which means a modern engine is far more optimized for both power and economy than anything was in 1995. The "easy" stuff is now already included in the design.

Out here in Texas their everywhere bro especially in Houston it’s just a grey area around the 2018+ 300 that you don’t find any topics on and it’s crazy all because the pcm issue..and if you do there’s no history or backstory just a deadend forum or video. Just like the history on the sprintex a lot of grey area around them with the 300s but jeeps got them all over their 3.6 same with the ripp on the charger/Challenger it just wasent till recent till more people started putting them on their 300s and documenting it

I got you basically can’t improve what’s already improved to the max. Well that’s crazy and I ain’t rebuilding no pistons, rods, cams or getting a supercharger. Now that cost logically don’t make sense and I will agree on that just rather pay it off and keep it moderately basic. ill find myself in a muscle car which I’m leaning more towards a 17 z06 if ima buy an 8 I woulda got a 14/15 Chrysler 392 but that’s a large gab of abuse it coulda took and I’m not ready to deal with an expensive headaches that will be parked most of the time..

You might find a premium fuel tune. The stock calibration is for regular fuel and retards timing if there is a knock. I don't know if anyone has developed one for the 3.6, but it would require an unlocked PCM.

I’ve read with that most people suggest a fuel injector and fuel pump swap if they get the trinity 2 premium gas tune with an unlocked pcm definitely was looking into that. very small gains for a couple of grand

 

[tomdstroud]

You need a WB to make any gains with a DS handheld. That would have to be installed in front of the cat.

 

[Curious Joe]

That says it all right there.

We get a lot of that here at Allpar. "I've just hacked my car to hell and back, and now it won't run. Please help me figure out why it's not quicker than a Hellcat !!!"

As others have noted, the only "mods" you can make, without spending thousands, is bolting on (or illegally removing) junk that only results in more noise.

But it gets worse. Modifying any of these newer cars will almost certainly void any warranty, and no dealership will even touch it if the exhaust or ECM has been mangled.

You're definitely stuck with this thing. You won't be able to trade it, and nobody else will want it unless you spend thousands to return it to stock. The idea of transplanting a V8 into it at some point in the future is not a realistic plan. You'd need a whole parts car to accomplish that, with the knowledge it would take to transfer all the correct parts, and the ability to make it all work.

It is, as they say, your car, do what you want. But - like so many others, you came here looking for advice.

Best advice? Leave it alone, and drive it.

I came of age during the 1960s and early 1970s. I recall the high compression V8s commonly available in the larger cars at the time, especially before compression took a dive in the 1972 models. Reading where the 440 Commando motors and 440 Sixpack motors made between 305 and 330 RWHP.

Car and Driver ran a very low mileage, completely stock 2019 Charger RT on the dyno to verify hp claims many readers had posted. Due to dyno issues, they realized 305-310 RWHP on the recommended mid grade 89-90 E10 and 315-320 RWHP on 93 E10. They felt the car would probably have better numbers once it was properly broken in.

I have no doubt about these numbers on my 2020 300s 5.7. Still a ways from being properly broken in and runs excellent on 93 E0. I'm truly impressed by the exhaust design. Crossover between the mufflers and an x pipe type design where the pipes go through the rear CatCon device. 300 is quiet and breathes well - a true pleasure to drive. I drove my share of 383 - 440 Furys - Newports - Polaras - Monacos back before they were emasculated. And my 2020 is far more modern in every way.

America will loose a great automobile when LX production stops at the end of 2023 - beginning of 2024.

The earlier LX cars and current LD 300/Charger and LA Challenger brought RWD performance back at Chrysler, which had gone 15 years without it, after they dropped the M.body in mid-'89.

We all know they have their quirks, along with some remaining maintenance issues, but they remain as popular with retail and fleet customers alike (Pursuit models have sold out in 2020, '21, and '22, and will probably be sold out on Day 1 for 2023).

You perfectly echoed my point about farting around with cars. Back in the day, when all we had were carbs, we could do a lot of stuff with them. On a Chrysler, we could adjust that Thermoquad 1000 different ways, and the same with ignition. Exhaust was usually straight forward, most if the HP models already had dual exhaust. Lots of guys would throw a set of hookers on and go.

These new cars already have all that. They have factory cold air. The ECM handles the mixtures and spark, along with charging and everything else. In the 80's, the highest performing V8 in the squads were tuned very conservatively, to prevent pre-ignition and overheating. 35 years later, it's all balls to the wall, and you can still get close to 20 mpg if you're careful. The V6 cars are rated at 300 horses, 50 more than the last Crown Vics and the '78 Fury 440 Pursuit.

A lot has changed, no doubt about it. If the guy was talking $5,000 instead of $1,000, then there's real fun to be had, and the first thing I'd do is find a stroker kit. Torque is what wins, and the 3.6 is a wee bit shy there.

Recalling the final E86 440s (A38 police package) were down to 195 RWHP despite full dual exhaust. Officially 255 net hp in 1978 - gone for 1979. E58 360 motor became the top Mopar offering, 220 net hp, 185 RWHP.

I ran across the following. 1970 Newport '440 Special Edition'. Fuselage Cars were truly beautiful. If I could turn back the clock. I recall one neighbor had a '73 Fury GranCoupe while another neighbor had a '72 Monaco Brougham Sedan. My parents had traded our '67 Newport Sedan and '69 Olds Royale Coupe for a '71 Sedan De Ville - a brand new design for 1971. The Monaco Brougham family had nothing but Chrysler products, including their extended family. Those days were truly special for Chrysler Corporation.

I admire your enthusiasm. Tell us what works.

Unfortunately some car models and engines did not get the attention of the aftermarket performance world. From the mid 90's thru the introduction of the "HEMI" Chrysler 3.5 , 3.6 engines ware totally neglected. The PCM's were virtually imposable to crack into to tweak and no one cared. Intrepid/300M/ LH and early LX platforms suffered along with the Prowler. Other manufacturer's such as Ford/GM were easier to wake up like the "good old days" so that is what they concentrated on.
My "anemic" 300M is as it was when new, my 78 ElCamino is a whole 'nother story.

I have a 19 Chrysler 300s v6 rwd.
Ive owned the car for over a year and throughout the time I’ve added parts and customize stuff here and there like I removed the fog lights and installed the stock fog light covers but with air vents drilled at 3/4 of an inch throughout the center of the covers allowing more air to the CAI and I also removed and customized the air Duck pointing it straight at the vents and not facing an inch away from the corner of the bumper like they do out the factory so now it’s got straight air access all the way to the Air filter, I’ve also bought a roar pedal commander, A K&N CAI, 80mm ported throttle body and ported lower manifold (haven’t done the top, because I hear there’s really no difference in the factory and ported one because theirs nothing to port) but that’s another topic.. also I’ve cut/deleted the resonators off right after the exhaust (might add the flowmasters 10s and remove the catalytic converters after the tune but I’m still up in the air about it) does anyone have the same set up or similar set up to what ima do but with the Intune 3 (or any tune) / with a pcm set up? And if so how big is the difference in performance? I’d imagine a good amount right?! because so far the stuff I’ve done to my car I can say changed it a lot from when I first got it at the dealer till now. stock R/Ts have problems getting away from me and on a straight away pull I’m right there at their back door not even a car length away (no offense to our hemi Mopar brothers, my buddy doesn’t mind the runs)..
and if so can someone who’s personally bought the tune/pcm themselves or installed their own tunes help me, I’m looking for a solid site. Nothing that’s shady or that haven’t been mastered yet..
Thanks guys

There is no tuning that can be done to the vehicle to increase it's performance. None at all. There is no point in trying.

The same goes for the exhaust. No amount of exhaust modifications will increase it's performance.

Your options are to sell it and get a V8 car, or get a supercharger kit for it. Here's one example: 2018-2021 Chrysler 300 Supercharger System

You can search YouTube for other people that have installed the RIPP supercharger. It's not for the light of heart and will cost over $10k - $6200-ish just for the supercharger kit. That doesn't include installation or PCM tuning, which will require that the PCM be unlocked - on these cars, the PCMs are all locked starting with (I think) the 2015 MY.

IMO, selling the V6 300 and getting a Charger R/T or Scat Pack will be more cost effective.

Don't go with the supercharger wait until next year and for less money you can buy the new Stellanis twin turbo in line 6 and drop right in there... automatic 525 horsepower

I just posted another on here still questioning this 😂 because after some runs with more HP/lighter cars the weight to power ratio is not adding up.. did I get a special v6?🤔😂 I’m just saying these mods gotta slightly do something because there should be no way Im beating lighter/More HP cars in my boat..
