Ford Super Duty F-250 & F-350 Diesel Mileage Blocker — 6.7L Power Stroke Guide
The Ford 6.7L Power Stroke diesel is America’s most popular heavy-duty diesel engine — and it’s also one of the most heavily tuned. Whether you’re running EFILive, HP Tuners, or a Spartan tuning kit, every dyno session and performance test adds odometer miles. A Ford Super Duty diesel mileage blocker from Mileage Blocker USA keeps those test miles off your history.
6.7L Power Stroke — Why It Needs Specialist Coverage
The 2025-2026 6.7L Power Stroke uses Ford’s latest SCR (Selective Catalytic Reduction) emissions system, variable geometry turbocharger and Ford Pro Intelligence telematics. These systems store speed and distance data across multiple dedicated diesel management modules that standard mileage blockers miss entirely. Our device provides full coverage across all Power Stroke-specific CAN-Bus modules.
Popular Diesel Tuning Scenarios
- Stage 1-3 tunes — power output testing on a load cell dyno
- EGT and boost testing — extended dyno pulls for exhaust gas temperature mapping
- Towing capacity validation — testing upgraded towing capacity with fifth wheel setups on private land
- Delete and DPF-off builds — off-road use only builds that require extensive dyno validation
