Im wondering if I could buy the stage 2 kit from ZZPerformance and tune it with the GM tune. I work at cadillac and im able to do the tune myself and its free! This is why im asking! Also do I need header and DP? I have a cat back and air box mod right now.

Thanks for the input in advance

 

You don't need exhaust work to run the stage 2. it will work with the GM tune if you get 42# injectors but it wouldn't be the best idea.

The ZZP stage 2 tune is much better than the GM and our kit comes with 50# injectors over the GM 42's.

 

50# injectors will take you a lot farther than 42#s

 

Now if i tune it with zzp dont you charge an extra 200. Or do I get that back? Also how long would it if i just sent mine thats in my car to you guys? Im in pittsburgh.
