2014 RAM Big Horn 4x4 Quad diesel
I can’t speak specifically to DEF, EGR, etc. But I can comment on the overall improvements with the EPA-compliment GDE PCM/TCM tune.Now that this tune has been out a while, can we get an update from the early users? Anyone with problems? DEF usage? EGR fails? How clean is your oil?
I bought a 2014 ED with the typical cold turbo lag, dead pedal, and jerky shifts. It got better when warmed up, but always a little sluggish until I put my foot into it.
The GDE tune addressed these issues and really woke it up. No turbo lag, a nice linear pedal and smoother transmission shifting with less gear hunting. The transformation made driving fun.
I was reminded of how much the tune improved driving when I re-flashed to the OEM to get the W58 recall completed. The truck was back to being like a grumpy old man waking up. No fun at all.
The GDE update following the W58 was easy to install and again made driving my ED enjoyable.
IMO, the tune is one of the best ‘bang for buck’ improvements out there. FYI they do offer a military discount.
