We here at Hardway Performance are proud to finally release a tuning option for current generation of Ram trucks equipped with the 6.7 Cummins engine. Currently only available for 2019 to 2024 model years and 2500/3500 pickup models only. Cab & Chassis offerings will be coming very soon once further development is complete. 2022 and newer model years are supported with a ECM replacement.

• SIX total shift on the fly power levels, accessible by utilizing the cruise control buttons on your steering wheel, no holes to drill or third party switches needed!
• Increased pedal response and drastically improved overall drivability.
• Removed speed limiter - for when 102mph just isn't quite enough.
• Exhaust Brake Memory - tired of having to turn your EB back on how you like it every time you get in the truck? Not anymore, it'll stay right where you left it last.
• Included transmission tuning (68RFE only) - Line pressure increased from stock 160psi to 170psi with transmission builder specific calibrations available up to 250psi, L/R clutch fix to solve sprag rolling issues, UD air test disabled to prevent bind up with increased line pressure.

An HPTuners MPVI2, MPVI2+ or MPVI3 with at least 6 universal credits and an HPTuners Smart Bypass Cable OR a Hardway 2018+ SGW bypass cable as well as a windows based computer with an updated version of the HPTuners VCM Suite installed.

This line of calibrations has undergone extensive in house development including hundreds of hours of dyno time, hundreds of internal revisions & thousands of road miles across several trucks in order to deliver you, the end consumer, a very well rounded and polished final product. To wrap up our development on this platform, we hauled a 2019 2500 Standard Output (68RFE) truck all the way from Florida to Southern California to the SEMA Garage to take part in their SC-E program. While being tested at the SEMA Garage, the truck underwent a stringent 6 week+ independent product test to not only ensure the product performs as advertised but also is within compliance to be sold as 49 state legal / EPA Compliant product and simultaneously obtaining the proper test data and documentation to submit to CARB to obtain an Executive Order (EO) which will make Hardway Tuning 50 state legal!
