That is THE only thing I HATE about my 2015 Ram! I long for a throttle cable! I won't waste my time on a PC and why spend the money on "tune" to a truck with 237K miles on it that is mainly used for towing? Did I mention that I HATE drive by wire?
The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.
