going to be getting my car tuned within the next couple of weeks, and was wondering if i should tune for the 3.4 or 3.5 with the following mods, 3 inch DP, intake and powerlog and cooler plugs.
 


Id think you could get away with a 3.5 on that setup. Ideally you might want to scan first and see what you have for KR and timing now.
 
I wouldn't even bother switching from a stock pulley until you get at least a PLOG with that DP or headers. Crank the timing on the stock pulley and enjoy not having hardly any parasitic loss compared to others and be almost as fast.
 


3.5... You probably won't be able to raise timing much except in cruise, but that 3.5 with a decent tune on your dp/powerlog setup should do fine. Yes, the stock pulley is pretty good for almost stock cars, but usually you can't get into the low 14's on a stock pulley with gobs of timing and running a lil leaner.
 
i have the power log on it already and everything, and i need a tune no matter what since i got an INTENSE PCM and they really messed up my WOT shift points. so i guess 3.5 if i do drop?
 
A 3.5" and 3.4" really aren't going to make that much difference. Either PM Reptile about a PCM tune or go buy a DHP PCM from 3800Performance.com
 
i have a place 5 minutes away that tunes GM and knows what they are doing so im planning on going there since i have to get other things fixed on the car -_-
