These are mods that you are considering? Or mods that have already been done?
Does your county require a catalytic converter be present or OBDII emissions compliance on a 20 year-old vehicle?

IF you want to upgrade to a better performing PCM, I'd suggest you contact fellow member Myckee. As for the other stuff, I have no idea. My 03 GT kept me happy with the way it performed stock.

The fellow apm member was likely myckee. He can tell you if he staged it. If these are things that have been done and it runs good then lucky you, that's expensive stuff.
the blow off valve may/may not be useful. the catless downpipe would be good for less restriction if your state allows it. from what i have done/understand you would either get a hot pcm or tune yours with a trinity with someones better software. the injectors would probably only come into play with a very extreme tune. my 2cents

newbie to all this
list is a framework to upgrade
03 gt auto. NEED opinions
thank you
Funny i went thru the same feeling when i got my GT! But, i eventually have done nothing. The thought of all that hp is beguilling cause you'll likely never use it. I might do a st-1 pcm flash, 3 inch exhaust would be nice to go with it, but i found on my project GT (CAR#2) to just cut off the muffler, turbo cars can go muffler less with minimal noise increase, youll be surprised. The pt is hard pressed to match the srt-4 stages because of small engine compartment. Besides- what does an srt4 do with 500hp? (Many have achieved that mark! ). The bottom line for me is that without spending money on parts i could by a 2nd gt to tinker on and i have. Besides GT #1 is near pristene Dream Cruiser4 5 speed with low miles, i don't want to mess it up!
