OK. I know this subject has been beaten to death lately, but for those of you with custom tunes:
I have a 2003 silverado z-71 with the 5.3, 3.73s and a 6" lift. AND, I'm confused ====>
When you get the custom tune:
a) Do they send you a device that reads how you drive and how your vehicle performs and then you send it back and they send you back a modified pcm??? If not, how does it work?
b) What aspects would need to change if I wanted increased gas mileage and horsepower?
c) What are some interesting things that YOU have changed with a custom tune to increase the performance of YOUR truck?
Sorry to blow this subject up, but I have read hundreds upon hundreds of raves and rants on this and am still about as clear as mud on the subject.
THANK YOU GUYS
