I have a 2014 ram 2500 with a mm3 tuner and egr/dps delete from ray. I have had no issues at all since installing everything back around November 2017. All of a sudden today while leaving the store I have no throttle response. I only get 50 rpms more at full throttle vs idling. The throttle position on the tuner shows it going from 0 to 100 percent when I press the pedal but nothing happens. Any ideas?
