I put 4.88 gears, front and back, into the beast and now need to reprogram the PCM to correct the speedo. Is there any product available yet?
He said the gears really woke up the motor and the low end. It would drive me nuts though being at 2500 rpm at 70. I drive 80 pretty regularly and 3000rpm would be loud for me, even with a Corsa non-droning exhaust.
Took 3 years to figure out how to fix the speedo on the rams? JesusDid he ever get the PCM updated correctly? Was it really as easy as Hypertech tweaking their stuff?
Hard to believe... it took us nearly 3 years with the new Hemi's to be able to change gearing.
Apples and oranges, I know... but dayum that's refreshing to see how easy it might be with these trucks.
