This talk of not tuning anything is always been pretty lame, there is plenty of room left in a stock tune vs. a custom one...just because it doesn't knock, doesn't mean the tune can't be improved on. MAF tuning needs to be done as well if your not running a stock throttle body or MAF...the PCM just can't re-learn that...been there, done that with my LQ4
apples to oranges...

Just because you are fixing mechanical issues with a 3.4 pulley car with the PCM..... it does not mean you HAVE to tune it to go fast.

We had super mild cars in the 13's with pcm's back before tuners were around... When the tuning thing got popular... we might have been able to get another tenth from faster shifts/less shift managment.

If your timing is 16, and your fueling is right.. you cant tune more power into a car.
