Yosh!
So next week sometime I'll be getting the GMS1 Kit installed in the 09 Cobalt SS/TC. The only thing I have on the car is a K&N CAI and a ZZP Catless DP waiting to be installed in the Garage. What power gains and boost should I be expecting from this kit? Because I could get the GMS1 through work I could make 4 payments on it so that's why I didn't go HP Tuners because chucking 700 out all at once hurts the bank. Lol

Why don't you find someone to HPtune your car? Hp tune is better than gms1. How much are you going to pay total for the gms1?

Lol this is not the car for you if you have to make payments on GMS1.

Secondly if you buy the connectors from CED you can skip the crazy install price from dealer
