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.

Had this for about a month in my 04 Ram 2500 5.7 and could tell immediately a little extra punch on the throttle. I think I like the modified shift points the most. However, running in 87 octane mode the whole time and lost about .5mpg - I was sort of expecting a little improvement here. It does seem to idle a little smoother too.
