Absolutely worth every penny. My 2017 XT5 just woke up. I let my son drive it afterwards and he asked what all I had done to it. I have only added the Airaid closed intake system…

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…

Had a couple of glitches flashing the cal -- all due to misunderstandings on my part -- but Trifecta tech assistance got me through them quickly, and the cal was flashed easily. …

I got the tune, installed it, it only took about 20 minutes, then the fun started, best bang for the buck, I've had in a long time !

Bought the trifecta tune for my 16 regal a few months ago. Didn’t actually plug it in until last night! The difference is like night and day. Product is worth buying.
