MKB's +38 hp ECU upgrade.
MKB's warranty is for the ecu only. That means if the ECU were to be replaced due to an issue with the MKB tune files, MKB would replace it a no charge.
MKB offers a NO CHARGE reflash if for whatever reason your ecu is flashed over by your Mercedes dealer. This may happen if Mercedes requires a total ecu update, this would eliminate the MKB flash.
As for the horsepower, our measurement is at the crank - as is Mercedes. The wheel HP will vary based on what dyno you use, and the experience of the operator.
Which forum are you talking about the group buy? How are things going in getting people on board?
Best Regards
