Extend your transmission life and increase your fuel economy with PPEI Transmission tuning! A MUST for tuned trucks with additional torque.
The refined shift points get rid of the low rpm “Lazy” feel these trucks have that force the driver to stab the throttle for a downshift – not cool and a fuel economy killer! For vehicles with larger turbochargers, ppei transmission tuning is a must to get the engine back into a rpm range to match the torque curve of the new turbo.
Along with the improved shift points, PPEI also refines the torque converter lockup strategy to put the power to the ground much more efficiently for improved fuel economy by eliminated unnecessary slip in the torque converter – which also drives down heat in typical “unlocked” conditions.
We at PPEI take pride in our work and if there is anything you wish to have changed in your transmission calibration, we are here to make it fit your driving style - "Custom Fit"!
This can be installed with EFILIVE
