2001 – 2010 Allison TCM Tuning
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.
