as far as the truck moving is this when you are idling on blocks or are the tires on the ground? i had the same problem with my sv pro when i had it on the block and it was at idle it would still move the wheels no matter how far down i turned the idle screw (it would kill the engine) before the wheels would stop moving. as soon as i put the truck on the ground it would just sit there and idle. just thought it would help if i shared my experience on this matter
