I own a 2011 1.8l Cruze and I recently installed the Dual-tip cat back magnaflow exhaust system with an Injen cold air intake. I want to get more power out of the little engine now. So i'm looking at the trifecta tune. Has anyone had any luck with it? What are some of the gains you're seeing? How hard is it to tune your car? And is it bad to run a performance tune on a car that will see many miles? Put 100,000km on her in the now 3 years I owned her. Thanks for the help.
