yes, many of us have.

its a valuable tool to remedy lethargic throttle control and responsiveness when daily driving.

i have used these modules in literally every car ive owned since 2012.
Wranglers
Hellcat
BMW x5 v8TT
Audi S6
and my powerwagon

its a great way to alleviate your hatred of stock transmission tuning and throttle mapping, BUT in no way is it a replacement for a true transmission and PCM Tune.
Its only temporary fix until your confident enough to get a real tune.

With that being said, you will probably still not love the throttle response. This 6.4 has plenty of get up and go, and the power is there. Its simply the MPG saving, transmission and throttle map tuning

So what i get from your response is a tuner is a better option? I have been looking at the pedal commander myself, but i feel like its a temporary bandaid and i will get used to it and then not like it again or want more. And the PC is 300 and i can get a diablo tuner for around the same price if i trade in my old one so i think when the time comes i will do the tuner instead.
