This is a single tune: one custom 50HP file for your 2023-2026 6.7L Powerstroke, flashed through EZ-Lynk. It is the lower-cost alternative to the standard 4-Week Lynk package, which gives you access to all of Peakside's tuning. It supports Standard Output, High Output, and Cab & Chassis trucks, and installs through the OBDII port with no ECM swap or under-hood connections.

Part Number: AA-PEAK-PS67-EZLNK-0HP-LTD

How to use high idle:

1. Start the truck and leave it in Park with cruise control switched off.
2. Press and fully release the brake once after starting, with your foot off the accelerator.
3. Double click RES/CANCEL and high idle will start at 1,000 RPM.
4. Use SET+ and SET- to raise and lower the idle 50 RPM per press, up to 2,000 RPM.
5. Press RES/CANCEL to exit. Pressing the brake, shifting out of Park, moving, pressing the accelerator or turning cruise on will also turn high idle off.

High idle resets to off every time the truck is restarted.
