Tunes, Diagnostic Tool, and Scan tool all on one device. You need tunes that match your truck and we have the best. Motor Ops has spent countless hours fine-tuning these calibrations so your DPF and EGR-deleted truck performs at its highest potential while maintaining excellent drivability, low EGT, and smoke control. Customers have been raving about this crisp, responsive tuning that lugs strong and pulls relentlessly to redline. The Motor Ops Auto Cal comes with five tunes, hardware, and OBD-II and USB cables. The tunes included with this product are listed below:

1. MPG: Stock power level, but with a refined timing and fuel curve strategy for optimized mileage.

2. Tow Tune: +40-rwhp over stock. This tune is built for towing loads of 8,000 pounds or more (i.e. “heavy” tow tune). 

3. Tow Tune (up to 8,000 lbs): +60-rwhp over stock and the ability to maintain transmission health and low EGTs with loads up to 8,000 pounds (i.e. “light” tow tune). 

4. Sport Economy Tune: This tune offers the best balance of power, reliability, and mileage on an unloaded truck. It is the highest level we recommend without a lift pump. Typical gains when running this tune are approximately 120-rwhp.

5. Race Tune: When used in conjunction with a lift pump, this tune will get the most fuel possible out of the factory CP4 high-pressure pump. Typical gains when running the Race Tune are approximately +150-rwhp. Emissions equipped trucks would be down 15-20-rwhp in comparison.


*DPF/Emissions Delete - Race Use Only. This product does support emissions removal for trucks that are intended to be used for race use only. It is the responsibility of the customer to know their local laws, and adhere to them. Motor Ops is not responsible for the unlawful use of this product.

**Beware of competitor HP ratings. Our gains are verified at the rear wheels using the factory turbocharger and factory high pressure pump. They're not flywheel estimates or potential gains with additional part upgrades.
