In addition to its engine repair and tuning services that enhance the performance of diesel engines while ensuring fuel economy, Diesel Spec also offers off-highway tuning services to reach unmatched high levels of performance.
Diesel Spec offers off-highway tuning services for special applications such as competitions and events like drag racing and/or sled pulling. In most cases, engines used in competitions require modifications, including the replacement of parts and the removal of emissions components. We put at our customers’ disposal a variety of high performance Big Boss parts: Turbo Chargers, Manifolds, High Torque Clutches, and more. Newer engines require the removal of the Regen System. Our tuning alterations include EGR Valve Delete, DPF (Diesel Particulate Filter) delete, Urea system delete (DEF Fluid), VGT Turbo delete (Variable geometry turbo) and RPM limiter removal. By removing these components from your engine, you will significantly increase the performance of your diesel engine when using your heavy truck for off-highway purposes.
With the deletion and alterations of some of these performance parts, your engine can easily reach over 1000 horsepower.
Diesel Spec tuning examples:
- EGR valve delete
- CGI valve delete
- DPF delete
- VGT delete (Variable Geometry Turbo)
- SCR urea system delete
- SPEED LIMITER REMOVAL
- RPM LIMITER REMOVAL
- TWIN TURBO CONVERSION
There are many other tuning alterations that can be made to your engine. Tuning allows you to reach new heights when using your heavy truck for personal purposes or closed-course racing.
Custom tuning available for competition trucks and export trucks using high sulfur fuel.
Truck export to countries with high sulfur fuel
Most countries still use high sulfur diesel fuel. All North American trucks that were built from 2007 to date, equipped with an EPA07, EPA10 or EPA13 certified engine cannot operate on high sulfur fuel. If they are using high sulfur fuel, their engines will only run approximately one week. During this time, the DPF will become completely clogged with soot/carbon and the engine will shut down.
Diesel Spec has the solution – completely cancel the after-treatment system (EGR-DPF-SCR). As a result, the truck engine will perform normally without having to go into derated or shutdown mode because of engine codes.
Most of our tuning work can be performed remotely all over the world with the purchase of Diesel Spec tuning tools. This means that you won’t need to ship your ECM to Canada and wait for a week. Therefore, you will save both on shipping costs and downtime. Once you are equipped with our DSI remote tuner, the tuning work can be done in just one hour.
Our Off-Highway Tuning services are intended solely for closed-course racing and off-highway driving. They may not be street legal in your province or state, and these services cannot be performed on vehicles registered or certified for highway use. Please check your federal, local, and province laws before purchasing.
