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...
