2007--2009 Pontiac Solstice - 2.0L Turbo - Advantage+

Installed Trifecta Advantage + on 4.25.21 in my 2007 GXP with 70,000 miles. Took all of 15 minutes. EASY TO INSTALL.

Noticed instantly the increase in power. Was 15 to 16 psi boost max., now 21 psi.

Pulls much harder at all rpm ranges! Automatic transmission shifts quicker now and can easily break the tires loose when punched at takeoff.
As for increased gas mileage some talk about, I couldn’t tell you because I can’t keep my foot off the gas now.

Was an enjoyable car with decent power, now it’s way more fun to drive. There may be a conversation with a nice police officer in my future. Ha

Well worth the money if you love driving your car! A Very satisfied customer.

I was really skeptical about this tuning service at first, especially when I got a check engine light the day after I flashed the tune. I was positive that the tune might have had something to do with it but after a bit of research I found out that the check engine light was caused by my stupid ass refueling the car while it was still running which damaged the EVAP Solenoid. Since then, I've continued to drive with the tune along with 2 additional bolt on modifications to my engine's air intake system. The tune has improved my gas mileage (22 to 25 avg. mpg) and increased power A LOT! So much so, that I'll be needing to upgrade my clutch to a much stronger one to handle the added torque. I love my Trifecta tune and their costumer service is quick to respond!
