Bmw X5M Xhp stage 2 tune
Hey! I flashed my X5M's transmission with xHP flashtool to stage 2, in this video. This tune is very easy to install as you can do it from your own driveway. The software is very straight forward and walks you through installing the tune as you go. If you have a BMW or newer supra, make sure to check out xHP!
