Carbahn tune is BS. I did it and only got 60% of the HP they advertised and only 6% of the torque advertised. I had it dyno'd. Total BS. Probably going to sue them. Car runs fine of course because it basically operates like stock plus a couple percent. Literally only increased wheel torque by 6 lbs. Not worth the money whatsoever.
