My wife has a 97 ws6 with an airfoil, k&n and a fuel pressure regulator and underdrive pulleys, we are goin to spend inbetween 500 and 800 dollars. We want subframe connectors and a cutout for sure. Without getting into the exhaust what to you guys recommend. Is a programmer worth it with a 160 thermo? It also does have all the free mods with a descreen MAF. How does that effect these LT1s with the programmer(descreened MAF)? I havent done a whole lot of research on mods and which ones work the best on the LT1 I spend most of my time on the LS1 board so any help would be greatly app.! thanks.

 

If you wanteed to maximize your cash for power. Long tubes for sure. That is the best bang for the buck, besides NO2. But since exhaust is out of the question.....

If you want a tune I would suggest pcmforless, or madwolf, I have heard great things about their work, and their service.
