2007.5-2024 Cummins 68RFE Peakside EFI Live TCM Tuning Upgrade

Unlock the performance potential of your 68RFE automatic transmission. Peakside Performance TCM tuning is an essential upgrade for any modified 2007.5-2024 Cummins truck running EFI Live. This tuning dramatically increases the driveability of your 68RFE by precisely modifying and adjusting shift points and line pressure.
