how much power or hp increase can i expect from a skunk 2 im

 

it varies with other mods.
Try getting the whole thing i/h/e/tb because they work with each other, I think.

 

I have heard with with a fuel controller (vafc) and cam gears and proper tuning, you can extract quite a bit. also by raising your red line, but then again you have to back that up by valve springs etc..(blah blah blah).
but bolting on the sk2im alone, you might feel a loss in midrange power. I'm not an expert but that is just what i read on the subject.

on that note, i have a friend that runs 12's allmotor with stock GSR intake manifold.

 

Youre going to need to get some cams if you want to see some decent power outta that thing.

That, and search really helps on this one.

 

yeah i was thinking that too. I almost had my heart set on that thing, but i guess there is alot of other things i could get first. but tuning i guess would be the key for skunk2 im

 

you still gonna gain a nice top end from it even if you dont have cams and stuff. i say get it was one of the best mods i have bought.
