Upgrade your already tuned EcoDiesel ECM to Driver Selectable Tuning and receive the OBD flashing device. A DST Switch will also need to be purchased.
The 3.0L EcoDiesel is an impressive smaller engine with a lot of grunt! We’re excited to be able to offer tuning that will increase the overall drivability and FUN!
We recommend this for all A50 & T87 controllers. It has an aggressive Line PSI slope which will model a torque curve 100% above stock. The line PSI is modified in such a way that the truck will still retain good mileage yet hold high line psi (close to 245-300psi under full load) following this torque curve. Line PSI is increased across the board, so as a result, fuel economy may be lower in some cases.
The PPEI EFILive Allison TCM Tuning is a major benefit to all users regardless of their modifications. The TCM Tuning comes with an earlier lock-up strategy that ultimately allows for the truck to put all the power to the ground more efficiently than the stock TCM calibration would allow. As for those weekend warriors it can knock off .05 off your track times for stock transmission applications and even more time with modified/built transmissions.
