Hello, my name is Erick and I have a 2014 Chevy Cruze RS LTZ 1.4l Turbo. I build cars for a living and I want to keep my Cruze completely stock but I was looking for a little more throttle response and a little more power. I contacted Trifecta to ask some questions about the tune including, can the Dealer see it? Does it leave foot marks so the Dealer knows it has been tuned? Does it help with gas mileage? I do not want to lose my warranty. Steve at Trifecta reinsured me that I would not have those issues and that I would be really happy with this tune. So I ordered the Advantage+ tune. Wow was I surprised! They have super-fast shipping, super easy download and even easier upload into the Cruze. Out on my first drive after installing the tune and I already noticed a HUGE difference in power and throttle response. It shifts so much better and firmer also I do not have that "No boost" felling anymore when the AC is on high and the best part of it all is that I am up 5 MPG over my average. I have now put about 2000 miles on this tune and I could never be happier, passing on the freeway is easier and safer, Cruze is faster, and my MPG is up. Thank you so much Steve at Trifecta for all of your help and service.
