Probably time to update the data. If I'm reading it right, UTUNE is not offering any tune for model years 2014 or 2015, SFR's have issues, Pross is not in the US, so this leaves BTR and RCCT.
I have a couple of questions. But first let me mention that I have a 2008 Sky Redline that has a Trifecta Performance tune. With only a HF Cat installed I'm getting 340/410 (at the crank). I can hit my cruise button and turn the tune off and on any time I choose (handy when I take it in for service). Also, I installed the tune myself via my laptop. Trifecta sends the tune via e-mail, you download their installtion software from their site, I downloaded it to my laptop, hooked it to my OBDII port, and voila, my redline was tuned in about 15 minutes. It is also totally invisible to the dealer if the ECM is scanned.
So, that all said, I have a 2015 SXL with no mods, and I want to keep it that way, a sleeper, if you will. The 2015 boasts 274 horses stock, what can I expect to gain (hp/tq) by simply installing the tune on all stock components, second, how are these tunes installed, and finally, can it be easily turned off and on?
