2020-2022 Duramax LM2 3.0L Motor Ops HP Tuners MPVI Custom Tuning
Select from 3 power levels for your 2020 - 2022 LM2 3.0L Duramax. Motor Ops Tunes are engineered to unlock the full potential of your 3L Duramax with proven and purpose built results that you can feel.
Built with years of experience and development to ensure that your 1/2 ton Pickup or SUV performs in a clean, consistent, and reliable manner.
Our tune options are:
- Optimized Stock: ~5-10 additional RWHP - great for maintaining factory power delivery while dramatically improving the drive-ability and reliability of the vehicle
- Tow Tune: +25 RWHP / 60 ft lbs of torque - excellent choice for those who tow on a regular basis or just want a torquey bump in power over the factory calibration but don't want the Sport Tune. This tune will deliver a wider torque curve which makes towing a much more enjoyable experience.
- Sport Tune: +45 RWHP / 100 ft. lbs of torque - this is a great option for unloaded daily driving. This tune will push the vehicle to the SAFE limits of the factory turbo charger.
ALL TUNING IS DELIVERED VIA HP TUNER'S TUNE DELIVERY NETWORK (TDN)
We strongly recommend adding a transmission tune to your tune. Transmission tuning (especially on any 3L Duramax) will dramatically improve the power that is delivered right to the tires. This is where you can actually feel the power instead of it getting trapped in the transmission.
Our transmission tuning addresses:
- Torque Converter Lockup strategy
- Transmission line pressure
- Shift points
- Shift timing
