Reviews for Superchips 3571 Flashcal F5 Programmer for 07-18 Jeep Wrangler JK

This tool perfectly adjusted my OEM settings, not just for mph but also for TPMS as I installed truck rated tires with lower PSI requirements. It also has served better than my prior diagnostic tool at interpreting codes and clearing them. I’m submitting this review not within weeks of getting it, but after a few years as its value increases with each Mod I do and finding it covers that too.

Great tool

Very good item. Been using it for years now

Worked like a charm.

Should have done this years ago! If you have over sized tires on your Jeep stop thinking and get this tuner. Couldn't be simpler. Shift pattern and Gas milage very noticeable even when pulling my trailer.

Works great every time. jeep runs much better now that the shift points are correct with the larger tires. Running 35's with stock Rubicon gearing and it runs just fine. Speedo is dead accurate.

Just ordered

Perfect and easy to use

Very easy to use

This unit is a bit pricey but I noticed the difference in response in my JK within minutes after changing the tire size. Dropped the horn chip so now I can come and go in stealth mode. Also nice to be able to turn off TPMS when wheeling or if sensors do not communicate. Well worth it!
