Guyz, lots of useful information on these forums. I've been doing quite a bit of reading before I start tuning my '05 Avalanche. I've currently installed a CAI, Granatelli MAF, and an exhaust system. Right now, just trying to get the most out what I've got.
The question is this: I don't entire afternoons available that I can spend driving and re-tuning the VE. Does it cause any issues if I do 1-2 tuning sessions in a day, then upload a safe tune (stock or HPP3 or whatever) until I get another chance to tune again? I don't really want to drive around with an uncompleted tune.....
Also, I've seen conflicting information on various forums regarding VE tuning. Do you reset fuel trims between each scanning run or not? I've seen info that says do, and others that say don't.
