TestimonialsI added my Trifecta to the Sky RedLine and programmed it to use the traction button. I call it my "Jesus Button"EZ flash cable shipped asap. Great customer support system in place. My car has a K&N intake and some minor exhaust modifications. The tune complimented these modifications very…Much more responsive, and a noticably better power band, definitely makes the truck more fun to drive, and the customer service is excellent. the shifts are so much smoother …Trifecta as a company is excellent. Fast response to support questions Tune is great!
