My name is Chris and I live in Brevard County, Florida. I just purchased a '09 SS with GMS1 and Magnaflow muffler. If anything else has been modified on it, I am unaware. I look forward to getting to know everybody and learning more about my new purchase.

 

Welcome! Post some pics of the engine bay and we can tell you if it's stock or not.

 

I'll do that tomorrow when it's daylight. It all looks stock, looks like GM did some wiring stuff when they added the GMS1 into it. Is there a GMS2 and if so, how can I figure out if I have that? I found out I had GMS1 by the little sticker they added under the hood and the fact I hit about 24psi.

 

Welcome to Cobalt SS forum kurisutofa! Send me your VIN in a PM if you want me to send you the original build sheet. You can also PM me at anytime you have a question.

Welcome to Cobalt land. once you enter there's no escape

 

24 PSI is a custom tune, GMS1 won't ever hit 24 PSI. There isn't a GMS2
