Super easy, best bang for your buck. Took a few minutes to download the software on the FlashCal then off to the races. I put a lift and a wheel and tire package on my 2015 JKU. It calibrated the speedo and adjusted shift points so it pretty much drives like its stock but better. A nice thing too, for $90 you can upload you FlashCal and turn it to a flashpaq and get some power and fuel mileage settings. I did see an increase in fuel mileage also, and it works great with my air intake.??
