You basically plug into the tuning port and and follw the instructions on the android tablet as it records your engine & transmission settings. Use the android tablet to put in whatever program you want and it's done. It was so easy a girl could do it....lol...Anyway it claims to give an extra 100 plus horsepower. I didn't put it on a dyno before and after but the performance tune gave it amazing quickness a very noticeable improvement in power. It was well worth the price to me. Haven't tried any of the other tunes yet. I'm still having too much fun with the performance tune.
