PPEI Transmission Tuning – Extend Transmission Life & Boost Fuel Economy

Refined Performance for Tuned Trucks

PPEI Transmission Tuning is a must-have upgrade for tuned trucks with additional torque and power. This calibration refines your Allison transmission’s shifting behavior to deliver smoother operation, better response, and improved fuel efficiency — ensuring your truck performs exactly how it should.

Key Features

• Improved Shift Points: Eliminates the low-RPM “lazy” feel that forces aggressive throttle input for downshifts — enhancing both drivability and fuel economy.
• Turbo Optimization: Ideal for trucks with larger turbochargers, helping your engine return to the correct RPM range to match the new torque curve.
• Torque Converter Lockup Refinement: Optimized to deliver power more efficiently, reducing slip, heat, and wasted fuel in typical “unlocked” conditions.
• Fuel Economy Boost: Smoother shifting and reduced converter slip translate directly to increased MPG and lower operating temperatures.
• Custom Fit Calibration: PPEI offers personalized adjustments to match your driving style and performance needs — your transmission, tuned your way.

Installation Compatibility

Installation is simple using EFILive hardware and software. Compatible with:

• EFILive AutoCal V2 / V3
• EFILive FlashScan V2 / V3
