Welcome to Allpar. I read it, but don't believe it. The claims sound like marketing hype.
If any manufacturer could have eked out these double-digit improvements like this in economy and horsepower while passing EPA emissions requirements, they would have done it in a heartbeat.
It basically tricks the PCM in thinking the IAT (Intake Air Temperature) is different than it is. Thinking that it is warmer may lean the mixture for better fuel economy, while thinking that it is cooler would enrichen the mixture for more power, but poorer fuel economy.
It can't do both at the same time.
MSRP $399.99 marked down to $69.00 sounds like marketing talk to me.
The 100% money-back guarantee sounds like it may be on your side. If you try it, let us know the results.
Run a premium 5w-30 motor oil. 75w-90 synthetic rear hypoid oil. Tires at 36#? Avoid cruise control in hilly areas. Gently accelerate when no one is behind you and keep the speed down.

I appreciate both the welcome and the info, its very helpful as I run around trying to get my biz off the ground.

Someone else recently posted that they bought this device. Note that they make you give personal info to get info on the device for your specific car. That means that this is a phishing scheme, they will make money by selling your personal info to other marketeers.

This is not even a "performance chip", it's a 2-wire device. They don't explain what they do to improve performance, but you can bet they're selling you a 5 cent resistor to try to shift the air-fuel ratio. However, your computer will compensate for this and balance it out where it was designed to.

Therefore, the only performance gain you will get from this device is the immeasurable weight loss from the money that they remove from your wallet.

I will have to quote this argument, it cannot be more clear and useful. Take Bob's advice.

If you want proofs then go and buy one, open it and find out, it is a resistor that tries to make ECU think there is more air coming that actually is.
