Designed for current PPEI users who already have an AutoCal and Single Tune. A DSP5 switch must be used to allow switchable 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 across the board, so as a result, fuel economy may be lower in some cases.
The single tune upgrade is available for current PPEI users that wish to change their current tune’s HP level. Select your vehicle to view the options that are available to you.
