The all-new RUN VSE DPAC 7 Duramax L5P Tuning System delivers unprecedented diesel powertrain control, completely redefining how your truck starts, idles, performs, and protects itself. Engineered by Vin Specific Enterprises (VSE) for E42 2024+ L5P platforms, this isn't just another basic horse-power dial. DPAC 7—Diesel Powertrain Advanced Control—is a comprehensive, on-the-fly switchable calibration matrix. It is officially dropping for public release on Wednesday, November 11, 2026.
7 Selectable Modes. Total Control.
No more compromising between different setups. Switch through seven distinct positions natively using your factory steering wheel controls to dynamically adjust power, response, and engine characteristics on the go.
- Position 0: Anti-Theft Immobilizer Lockout — Total security at your fingertips. Dropping to Tune 0 instantly triggers an engine-kill sequence. The truck will not start or drive until you click back out of the slot (built with safety lockouts so it cannot be accidentally activated while moving).
- Position 1: Stepped High-Idle Control — Perfect for quick warm-ups and cold mornings. Automatically commands the CAN system to raise RPMs and seamlessly disengages the moment the truck is shifted into gear.
- Positions 2 & 3: Twin Sonic Profiles (Rumble & Hiss) — Get both signature sounds in a single package. Position 2 commands a deep, heavy rumble idle, while Position 3 shifts the variable-geometry turbo vanes to deliver that distinct, aggressive exhaust hiss.
- Positions 4 - 6: Multi-Stage Power Levels & Staging Limiter — Escalating horsepower and torque maps designed for everything from daily driving to heavy towing. Position 5 and 6 embed a built-in Boost-Assisted Launch Control / Staging Limiter. Floor the pedal, and the system locks the truck at your target staging RPM to stack massive boost without creeping past the tree.
- Position 7: Push-to-Pass Max Effort — Instantaneous access to maximum power. By holding the steering wheel up-button for two seconds, the system bypasses lower maps and throws you directly into Max Effort performance. A quick flick down returns you to your baseline.
Product Highlights
- Seamless Integration: Fully integrated with your truck's factory cruise/steering controls—meaning no clunky aftermarket knobs drilling into your dash.
- Dynamic Variable Vane Management: Unprecedented CAN-bus command over idle vane positions gives you real-time authority over exhaust notes and operating temperatures.
- Safety Interlocks First: Advanced software parameters ensure high-performance racing maps and security modes can only be triggered under explicit, safe operating conditions.
