Description

HP Tuners RTD4 + Peakside steering-wheel SOTF. Choose your tune level using your truck's factory cruise-control buttons. No separate manual SOTF switch is included.

Fits

2019–2023 Chevrolet Silverado and GMC Sierra 2500HD/3500HD with the 6.6L Duramax L5P and compatible E41 ECM. Not for 1500 trucks, L5D medium-duty trucks, or 2024-and-newer applications.

Included

  • HP Tuners-branded RTD4 remote tuning device.
  • Peakside steering-wheel SOTF ECM tune file for your VIN.
  • Six HP Tuners universal credits for ECM licensing.

The supported E41 workflow uses HP Tuners' direct OBD upgrade with RTD4; an ECM mail-in service is not part of this package. Set up TDN and wait for Peakside's invite code before connecting for the tuning workflow.

Before ordering

Enter your 17-character VIN and complete the vehicle check. VIN decoding checks year, make, model and engine; controller compatibility must also match the application below. TCM tuning and TCM credits are not included.
