So I got this cobalt SS a few months ago from a young boy that didn't know much about it. He got the balt from a dealer and only owned it a 3 months. Right off I could tell the balt had smaller SC pully 77.9 with blue bolts and the injectors are silver. I figured this was GM stage 2. After further looking into the car I found injen cold air and zzp short header and cated 2.5 down pipe also magnaflow 2.5 cat back. When I got the balt the boy said it did have a stock tune still and would need a tune. Since he didn't know any thing bout the balt how would he know this unless was just guessing. So my question is how do I find out if its tuned or not and what kind of tune its running if it has one. I have reason to believe it is tuned because my down stream 02 sensor broke and it will not throw a code for it and I know they delete them in a tune. Also I thought the stock cobalt SS Rev limiter was 6.5 when I can Rev 7.1. Can any one inform me thanks in advance Raymond

Give James a call like he said, he will get that car running right and have you happy with it!

 

When would be a good time to call I would love to get this balt running the best it can and I don't want to damage the motor if it is running stock tune this is my DD

 

You can call me in about 5 mins!

 

Definately has a tune if you can rev to 7K, the GM injectors have black plastic tops, not silver, so you might have something else in there.

 

They do have black plastic tops

 

Call me..if you can

 

I have this exact same setup in my car if I drop to a 2.9 pully will i have to change the injectors to say #50 and get a new tune? Or can i run with the #42 injectors and stick with the GM stage 2 tune...I am looking at meeting up with a couple guys in this area that can run your tune CCSS3..just curious as of right now!

 

I don't recommend 50s and never will... I recommend getting 60s so you have more availability.. But if you go to a 2.9, you'll need a tune for 42s anyway. So if you plan on upping the injector get 60s
