2011 - 2016 Allison A50 & T87 TCM Tuning

The A50 & T87 Allison follows a pre-determined torque model in which all factory LML Duramax’s follow. As throttle input and load increases, so does the calculated torque the TCM estimates. Following this estimated torque amount, is line pressure. Line pressure in factory form is PERFECT for a factory tuned engine, however, once torque is increased with tuning… The predetermined torque model is higher than what the transmission estimates and results is lower-than-needed Line PSI. With PPEI TCM Tuning we increase the line PSI to a torque model like it would have come with from factory – Which gives the transmission the line pressure it needs for the torque increase of the tuning.

**PPEI TCM Tuning - 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 higher across the board, so as a result, fuel economy may be a little lower in some cases.
