Since my nearest dealership is a solid 3 day drive each way I doubt any MMC people will get their hands on the ECU. If I did anything with it I would get an unlocked ECU mapped for the cams already..

We will see how it runs, and after all I was looking for a smooth running engine and not necessarily more power, but I did expect an upgrade in power would happen.


You can contact Garage56 or KrazyHorse to purchase the unlocked version...


Is your unlocked? If so who tunes it for you here or do you do it yourself?
