who else besides sts makes a turbo kit. i found one other but they dont have the carb oe numbers. so every time i have to smog the truck i would have to take it off.

I do, Nelson does, and Trick, but none of them have CARB approval. Only one is STS and its only on 01-05 I believe. AS far as what's better, depends on what you want to do with the truck. A 5.3 with about 7 psi of boost will make about the same power as a 408, but then you can turbo up the boost and make more power then a NA 408 if you want!
