For Added Safety, we are requiring the use of HKS M45XL spark plugs as well as two oil catch cans for the ECU tune.
** disclaimer: the vehicle from factory has a bit of a odd spot in the throttle where the car feels jerky, this feeling is due to how small the turbo is and this will NOT go away with the tune. Please be advised that this is a normal occurrence with the vehicle from factory and will be the same on the tune as well. DCT models will also notice that at very light throttle the DCT will be jerky as it tries to find the gear it should go into, this is also normal behavior from factory and the tune will not fix this issue. ECU tune may void your factory warranty and BTR is not responsible for any damage real or perceived.
***Jerkiness described above can be minimized with the optional but highly recommended boost solenoid
