Installing A RoushCharger On A 2004 F-150 - Pulling Power
|
One of the many things the RoushCharger has going for it is a complete factory-level flash of the ECM as part of the kit. The tune itself is a closely guarded secret, requiring you to ship the ECM back to Roush for the flash tune. We've read of some tuners "looking" at the calibration and finding it almost too good to mess with, meaning Roush did their homework and the tune will be spot-on for the blower install. Don't forget to disconnect the battery before starting on the tear down. We recommend removing the ECM and shipping it out first so by the time you're done with the install the ECM will be back from Roush. View Related Article
