SuperchipsFLASHCAL F5 IN-CAB TUNER,GASOLINE,COMPATIBLE WITH 2007-2018 JEEP JK WRANGLER

Did exactly as advertised. Very simple to use. Changing the tire size made it shift properly and I have gained 4 miles per gallon. I also eliminated that nasty tire pressure warning alarm. Awesome product, highly recommend.

Es caro para lo que en realidad hace y se necesita, tiene funciones específicas y actúa bien pero de ahí en fuera todo lo demás es simplemente para justificar el precio porque es caro

So for context I am using this on a 2013 JKU Rubicon 10th anniversary on 35's with 4:88 gears air intake and throttle body spacer. I owned a jeep off road and rockcrawler shop for years in a different time in my life so I have been around this industry working on nothing but jeeps for some 35 years. The programer is very easy to use and updates were a breeze via laptop. Being able to change both lighing options and more so speedo calibration with larger tires and the flexability of tire choices was key. The settings showed a noticable improvement when moving though the fuel setting and the throttle response in the 91 octane settings showed more snap to the pedal in real time. Menu's were easy to follow and load times were relatively quick but the gains immidiate. Clearing the syste also was easy in the event you need to sell the vehicle and had no check engine lights or diagnostic issues at all on either install or removal. SUperchips is a a proven on point company and with the many items out there I feel this product has the best gains for the money spent.

Tested and Works perfectly for the needs of my Jeep 100%.

Great product! Wish I would have purchased it sooner. Transmission is much happier now
