New Customer With 2007 C6 Coupe

I have just installed the perf tune and so far so good. I can notice a slight difference. Having a Callaway Honker installed, will the existing perf tune work ok or will I need a custom tune? Same question for headers.

Thanks

The CAI will work fine, the headers will require a tune.
We are planning to add longtube tunes to the U7194, but if you add them before we get that done, let us know and we will get a tune made for you.

Thanks
