PPEI L5P TCM Tuning 2017-2019

PPEI's transmission tuning optimizes shift points to eliminate the low-RPM "lazy" feel, ensuring crisp downshifts without excessive throttle input, which boosts both drivability and fuel efficiency. For trucks with larger turbochargers, PPEI's tuning aligns the engine's RPM range with the turbo's torque curve, delivering power where it counts. The refined torque converter lockup strategy minimizes unnecessary slip, reducing heat and improving power transfer to the ground for better fuel economy and cooler operation. Increased line pressure further enhances durability by boosting clutch pack holding capacity, providing confidence for tuned trucks or heavy towing applications.

With Edge Products' OBD-II flashing, you can flash your custom TCM tune directly through your CTS3 device, right from the driver's seat.

**This requires EDGE Products CTS3 Insight + device or EDGE CTS3 with the EDGE CTS3 upgrade for flashing -

To upgrade your EDGE Insight CTS3 to an EDGE Insight+ CTS3, connect the CTS3 to your computer, open the Update Agent software, and allow the device to update. Once the update is complete, the software will automatically direct you to our webstore, where you can purchase the Insight+ upgrade and download the new custom tune license for your device.
