i am not an expert by far but i know a couple people running pretty much the set up you described and all of them are getting around 300hp. so unless you forgot to list something you are about 100hp off.

 

maybe he is just gonna run a 150 shot of NOS!!!!!!!

 

hence me saying "unless you forgot to list something"

 

but with the gm stage 2 kit and reflash i should be able to run a 2.9 safely right?

 

get a custom tune if you wanna be safe

 

well, i havne't hooked my car up to anything, but people that have say that the stage 2 tune runs a little rich. look at your black ass exhaust pipe for proof

again, haven't tested it, but in theory the 2.9 would lean it out slightly bringing it into a more ideal a/f ratio.

 

Amen on the 3.20" size being the safest without a tune. Check them out on Sale here:
