I have an '07 SS/SC with GM Stage 2, axle back exhaust, and cold air intake. I just ordered a 2.9" pulley, 1 step colder spark plugs and a ZZP heat exchanger. I'm wondering what kind of power gains you guys think I'll get if I:

Run my car with the Stage 2 tune?

Get a custom tune?

Thanks in advance.

bump.

 

my friend did that an he said he saw a small gain but nothing to crazy you'd be better off gettin 60's and dropin to a 2.75 an gettin a tune

 

yep 60s and a 2.8 with a tune with the mods u just got and a dual pass will be a good start up set up.

 

Yeah i was thinking about getting a 2.8" but no one in my area does any tuning, and i didn't want to run the 2.8 on a stage 2 tune.

The to get my car tuned it would be like a 2.5 hour drive so it's kind of a hassle.

 

get a OTT can tune i heard its actually pretty good

 

You will see some smaller gains, but nothing insane!

 

There is a man in Regina by the name of Russ Kemp who is supposedly the man when it comes to HPtuners. I know a RL owner in Regina was lookin into getting tuned by him.
