hey guys i got the GM stage 2 kit now, but i wanna run the 60lb injectors and a 2.79 pulley. no coolin mods just yet, gunna do a H/E at some point but j.w if the GM tune will run well and will that be to much with no coolin mods?

 

1) If you're going to a 2.79" and 60# injectors, you'll definately need a retune.

2) If you don't upgrade the H/E and go dual pass, your IAT will be too high.

 

They do (for SC's) and it's great!

It keeps your warranty intact, which is part of what we paid for when we bought our car.

Doing anything else is = to throwing away money, which doesn't make any sense if there's an alternative.

Which there is ...

 

Cooling mods are a must! You can make all the boost you want but the more boost you make the more heat you make which cuts back timing and puts you in the same situation as a 3" pulley with no cooling
