I added a Stage 1 tune right away and was super impressed with the increase over what was already a quick ride.
Enjoy.


A definite boost increase. So much so that the car still pulls for a few tenths of a second after you let off the gas which was scary at first. Hoping to get it dyno'ed with and without the tune soon.
That dropped the 0-60 from 4.5 sec to 3.45 sec (both times with rollout like the magazines use).
Crank hp is supposedly about 550 hp and 650 ft lbs as I didn't remove the cats. Supposed to be 580/695 if you do)
Audi RS5's, Corvettes, Challenger Hellcats etc are dead meat from a light,.... and there's no gap you can't make when puling out of a parking lot onto a highway.
