Superchips Flashpaq for JK; Thumbs up
Thumbs up for Superchips flashpaq. Huge improvement for JK auto.
Shift points are perfect (no more trans looking for a gear), and way better acceleration. Dialed in my gears and tire size and my speedometer is now dead on too (GPS verified). The 87 octane tune shifts good and gives a little more acceleration, and well as slightly improving gas mileage (probably because the trans shifts less). The 91 octane tune runs like a completely new engine, very noticeable difference in power but no improvement in mileage. I have not tried the rock-crawling tune yet, maybe on a future run.
I would say the 5.13 gears and Flashpaq are the best things I have done to my Jeep. I was was going to start to build-up another JK, I would start here first.
