MotorOps DPF, DEF & EGR Delete EFI Live Autocal

You need tunes that match your truck and MotorOps has, perhaps, the best. Motor Ops has spent countless hours fine tuning these calibrations so your truck performs to its highest potential while maintaining excellent driveability, heat, and smoke control. Customers have been raving about this crisp, responsive tuning that lugs strong and pulls relentlessly to the redline. This product comes with five tunes, hardware and cables.

Unleash the Beast:

Choice of 5 Race Power Levels Including Stock Power & Tow Tunes with up to 540 RWHP of Switch-On-The-Fly Power at your fingertips with the optional LPS Switch.

True & Verified Horsepower Gains

Beware of competitors HP ratings. MotorOps verifies their gains at the rear wheels using the factory turbocharger and factory high pressure pump. They're not flywheel "estimates" or "potential" gains with additional parts upgrades.

Easy Plug-N-Play Installation:

Simply connect the AutoCal to the ODBII Port using the included cable and follow the directions on the AutoCal.

Read and Clear DTCs (Diagnostic Trouble Codes):

Save money and needless trips to the mechanic by troubleshooting in your driveway.


Whether you are into 1/4 mile performance testing or desire to see how different driving styles effect your truck's fuel economy, the EFI Live AutoCal can create data logs that can be viewed on the device or downloaded to your computer for deeper analysis.

Switch-On-the-Fly Cable:

The SOTF Cable allows you to load all the tuning on the truck at once and to change your tuning on the fly. Going from a heavy uphill tow to highway cruising, simply dial in the required tuning without stopping and waiting for tuning to load.

OPTIONAL Transmission Tuning:

Our precision transmission calibrations are set up for optimal performance! Keep your truck in its most efficient RPM range. Reduce smoke, EGT's, turbo lag, and track times! Improved throttle response and torque holding capacity! 2011 to 2016 Allison Transmission calibrations will optimize shift points and torque converter lock up, reduce shift times, and increase line pressure. Our transmission tuning offers you the highest level of performance and drivability in both stock and aftermarket transmissions!
