You think I can pick up a extra 10-25 hp over the wester's tune I already have in there? Or the stock tune that came from GM?

 

I gained 33/33 over the Westers tune

 

Really, I guess getting a tune done in person is worth it. They only charge $200 for a tune. I wish I found them before I tried a wester's tune and the wait4me tune. I just hope I can notice a difference since my truck is mainly stock, not like yours where it is modified. The guy I have been talking to, said they tune about everything. Supposidly one of the guys own a supercharged chevy silverado and it was featured on gmhightechperformance magazine. Do you any of you guys get that magazine? Because I would be interested in seeing it.
