2006-2010 5.7L to 6.1L Engine Swap Performance ECU Calibration

Upgrading from a 5.7L HEMI to a 6.1L HEMI in your 2006-2010 Chrysler, Dodge, or Jeep is one of the most popular and rewarding engine swaps. But a direct swap isn’t enough — your ECU must be reprogrammed to properly run the 6.1L engine. MoPower Calibrations offers a proven Performance Calibration Service that makes your swap seamless, reliable, and factory-like in drivability.

Why ECU Calibration Is Required

The 6.1L HEMI has different fueling, ignition timing, and torque management requirements compared to the 5.7L. Without recalibration, your swap may run lean, misfire, idle poorly, or suffer from incorrect transmission shift points. Our calibration corrects these issues, ensuring your vehicle performs as if it rolled off the factory line with a 6.1L.
