Trifecta tune with GM upgrade
 

I am curious if anyone has done the Trifecta Tune on their HHR SS with the GM power upgrade installed first? I am considering this but was wondering if GM would be able to detect the aftermarket tune for warranty purpose. I read somewhere in a thread, can't find it again yet, that GM is aware of these aftermarket tunes and have developed a program to detect them.

You would want the Hide-A-Tune and The Dual Tune is nice.
Never heard of a program to detect them yet, but GM will not tell us that.
