Question for MHP speed limit remover with ecu?
Reading you thread on your ecu only tune do you remove the speed limiter on c63???If so; what is the dyno top speed 7000rpm 7th gear?
Thanks for the recent offering to tune ecu only...looking forward to mhp products
Honestly the top speed in 7th is theoretical only as the motor could never pull such a tall gear with the present differential gearing. Redline in 5th was at or over 185mph.
