I have a 2015 Jeep with a RIPP supercharger that had been very tempormental with air/fuel ratios and had on and off performance. I had tried tunes supplied to me by RIPP and the local shop that installed it to no avail. Brought it to Dyno Comp and they were able to figure it out. It is now a different vehicle. It makes much better power and no more engine lights. I am not a racer or a gearhead - I am just a happy customer with a Jeep that now works thanks to this shop!!
