First off I have had a positive experience with flashing the 87 octande tune, adjusting tire size, TPMS threshold etc. on my 14' JK auto
The 87 octane tune definitely livened up the driving experience. throttle tip in is much improved. may have added some power in the mid to upper rev ranges, 4k and up. I have no plans on loading the other tunes

Tuning is straight forward. plug it in and follow the prompts.

I Bought a flash cal and upgraded the software via the superchips spark update service.

Flash cal. $153 shipped on sale
Software upgrade. 89.99
total cost: $242.99

Compare that with the flashpaq: $315+ shipping

Get em while they are hot.

 

I did the same thing, it is a great deal!
