It gives you the ability to remove federally mandated emission components. This includes the Diesel Particulate Filter (DPF), Exhaust Gas Recirculation valve (EGR), Diesel Exhaust Fluid (DEF), UREA, Selective Catalytic Reduction (SCR) & Catalytic Converter (CAT). With all these features its our most popular DPF delete tuner for the 2013+ 6.7 Cummins. When installing this tuner you must remove the diesel particulate filter (DPF) This on average increases your fuel mileage 3-4 mpg or more. The RaceME Ultra has 10 available power levels that can be changed on the fly (2010+ trucks only). If your not interested in additional horsepower gains you can still remove your factory DPF & CAT and retain the stock power settings. Not only is removal of the DPF possible; the RaceME Ultra will also turn off your EGR system without having to remove any parts. Tired of adding DEF fluid? After installing the RaceME Ultra the DEF system will be disabled and you will no longer have to deal with DEF tank issues. Have you changed the tires or gear ratio on your pickup? Re-calibrate the speedometer to accommodate for these changes. Also included for trucks equipped with the 68RFE is transmission tuning. If you tow 10k+ lbs. we suggest adding the pyrometer kit so you can keep an eye on your exhaust gas temperatures. All these features are available without setting a check engine light or diagnostic trouble codes. Online updates are available free of charge. Everything is included for a complete and easy install.
