First thing I was wondering if anyone has one or knows where I can get the performance computer for this truck I have one but it's bad. Second I don't know if anyone has ran into problem but when coming up to stops put the truck in neutral and coast to a stop the engine will almost stall and the rpms will jump from 1000 to like 300 and level off after 2 times the engine will do the same thing when it's warmed up and just sitting there.
