Add over 50HP/TQ with our custom tuning solution delivered via HPTuners! AFR, Ignition Timing, Torque Limiters, Boost Pressure, and more are all optimized to give you a massive increase in power while still retaining OEM quality drivability and reliability.
Transmission tuning is supported for certain service models, contact us for more details.
Included in your purchase is unlimited retunes for ALL products purchased through BNR website and BNR brand products purchased through dealers, as well as all minor bolt ons (intakes, etc.), regardless of brand.
One fuel type is included with your tune purchase. Additional fuel types can be added on at any time. Aftermarket forced induction tuning or engine swaps can be retuned for a fee.
BNR reserves the right to assess or waive retune fees at our discretion.
An HPTuners MPVI3 is required. RTD and older MPVI devices DO NOT WORK with the Global B platforms. ECM Unlock through HPTuners is also required. It must be the ORIGINAL ECM from your truck, it cannot be a spare. This is due to the security modules in the truck.
Tuning is a service, not a product, and is non-refundable once tune files have been emailed to you. Subject to discretion of BNR Staff.
