One of the best mods I've done!

I lifted my 2015 Rubicon and installed 35" tires. I drove it for a week or so before buying the Flashcal. Once I installed it, I was shocked at the difference in just the recalibrating made! I wondered why I waited the week! I also like the extra features and the display is nice and easy to read. Also the added benefit if upgrading to the Flashpac is cool as well.

I have a 15 F350 and changed from the stock 34" tires and went to 37" tires and installed the Speedo Calibrator. One thing to remember when entering tire info even if you look up the numbers in height. The stock tires are 34.1" vs the 36.54..you need to measure once the tires are installed on the truck and on level ground. My 37's once compressed are about 36.25 Entering this number got me closer to the real GPS on my phone vs running 2 mph slower at 75mph. Ill be using 35.75, to get it closer.

Lots of options. Upgraded to flashpaq. Ran into a little problem when my JK BIOS got corrupted but called Superachip customer support and they quickly trouble shooter the problem. Speedo fixed, gear ratios on auto tranny OPTIMIZED, LOW AIR PRESSURE ALARM CLEARED. Itching for gear ratio and Axel tweaks now.
