HPF STAGE 2 | 440KW

CHEV L5P 2500 SILVERADO 6.6L DIESEL STAGE 2 | 440KW

The Chevrolet L5P 2500 Silverado 6.6L Diesel Stage-2 upgrade starts with one of our trained technicians setting your vehicle up on one of our dynamometers and performing a baseline dyno run. This allows us to firstly make sure everything is working A-OK and secondly it gives us standard figure from your car to compare to once the upgrade is completed. Once the baseline dyno run is done, we then continue the upgrade by raising the vehicle on a hoist and replacing the rear exhaust section with a new higher flowing 4” Stainless steel item from MDRP in the USA, next we removed the standard air box and install a high flow air box from S&B Filters, also in the USA. The result is a high flowing air path both into and out of the big diesel. Next, we connect up the latest in ECU reprogramming tools which allows us to directly tune and optimize the trucks factory ECU parameters. The vehicle is then custom tuned on the dyno offering a maximum increase of around 35% in both power and torque over the already stout Chev diesel V8. The HPF upgrade features 3 switchable on-the-fly tunes that can be selected from the steering wheel. Details below:

We complete the upgrade process by testing your vehicle on the dyno and the road to make final adjustments, optimizing your vehicle's performance and driveability. This is all completed in a day and at the end of this upgrade you will be provided with a dyno graph detailing the power & torque increase of your vehicle.

Position 0 – Offering around a 10% increase in power and torque over standard, this is essentially the standard tune with some torque limiters altered. The fuelling is actually leaner than the standard tune file and is designed for heavy towing and improved fuel economy.

Position 1 – Offering around a 20% increase in power and torque over standard, this tune is designed for normal driving and light to medium weight towing and should also offer an improvement in economy as the engine is now making 20% more power and torque whilst still maintaining standard air fuel ratios.

Position 2 – Offering around a 35% increase in power and torque over standard, this is the highest performance tune we offer. This is not a towing tune as the fuel mixture is on the richer side but like all three tune file options, it still works happily with the standard catalytic converter and diesel particulate filter in place.

Notes

• Power figures are estimates only and actual figure's may vary.
• Power figures listed are estimated kilowatts at the flywheel based on results typically obtained by HPF on HPF’s dynos. Typically these are based of a manual vehicle with standard driveline and standard wheels and tyres. Actual power can vary based on each specific vehicle.
• Modifications such as this package require the vehicle to be in excellent mechanical order.
• We advise against increasing the power output substantially on high kilometer engines, if your engine has in excessive of 150,000kms please contact us to discuss options.
• Whilst every attempt is made to ensure prices listed online are correct, they are subject to change at any time.
• Additional parts may be required in some cases depending on the condition of the vehicle. Cost of these parts and additional labor required may incur additional cost.
