Re: Tuning A '96 4.3 V6 Vortec Engine - Help & Pointers Needed.
The reason to look through the blowers and bottles section is that this is where the most info is available for modifying these motors, the 262ci section seems mainly just a place to diagnose misfires and other odd problems, not much on the performance side like cam/head work. As for having head work done, almost any reputable shop in the U.S. I guess, I had a guy that has a machine shop in his garage do my head work for, installed 2.02 and 1.60 valves did bowl blend work and valve job. Then I picked them up from him and put them back on. And do not get a mail order tune, they are not going to be ideal for the head cam setup you will have, its best to swap in the 0411 and then have a tuner use hptuners or efi live to hook up to your pcm and scan it and data log then go ahead and make the adjustments necessary.
