I finally got my lazy rear end moving and bought updated Gearhead tunes to account for my KC turbo (Stage 1.5). Had to load the updater on my new Windows 7 computer (I know Windows 7 is outdated!) so I could get the tunes loaded on my old X3 device.
I drove it on the stock tune for about 15 minutes ................ Horrible experience!!!
Sure do like the SRL+.
