Ok so I知 in the process of building a turbo kit for my 98 c5. The goal is 650 rwhp. Now I read about sd tuning and maf. But being that I have a 98 I知 limited to tuning right? What are my options without going to a 99+ pmc? Also if I go speed density I would get tuned in Phoenix az which is 1,000ft above sea level. But I live an hour north of Phoenix with an elevation of 5,200ft. With a speed desity would I have drive ability problems? By the way my car is an automatic (4l60e). Will it still work properly? I have heard stories of burning them up on sd tunes.
