5.9 Magnum FI cam upgrade

Not sure if there is anyone on this sight that can do this. I'm sure someone will chime in if there is. I know you can contact "hemifever" on the Dakota durango forum. This is what he does. I don't know of any way to tune them yourself though.
HemiFever has a bad reputation from a lot of the Dakota crowd on forums that aren't named Dakota-Durango because of drivability issues.
