Just got my Trifecta tune finished on my 2013 Traverse LS AWD. I LOVE it! This is how these cars should run, from the factory! I like being able to turn it on and off, via the cruise control switch. As good as it is, it is very expensive, considering you don't get a handheld unit. You have to use a laptop to load it, and there are no adjustments. I was skeptical, but I bit the bullet, and glad I did. Haven't seen a lot on here about it, so if anyone has questions, I'd be happy to answer any questions. FYI
