2011-2016 GMC/Chevy LML Duramax 6.6L TCM Tuning | EFILive

$199.99

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.

This tuning package can be only be installed using the EFILive AutoCal V3.

PPEI is making great strides in expanding the performance of on-highway vehicles and only offers emissions compliant tuning.
