I can't help the fact you guys think im lying or being vague when i answer questions in short terms. If you want to know more about something ask me but im not about to tell you all a story every time i make a post.
I dont have a problem with any guy that tunes or claims to tune. Im just being realistic that some guy with a wideband clamped onto an exhaust pipe is going to do something that gm couldnt do in a $50million dollar test facility (whom many of my friends work at). I will always say i cant do much better than stock tuning on a stock car and ive been doing 3800 tuning years before will has... and im willing to bet he is using tools that i helped put together.
The simple fact is in closed loop the o2 sensor is the tuner. Will sitting in there doing tuning is completely pointless when the o2 sensor will change it back to whatever it was the second it has the chance.
