i have a problem. on level six the hot level when i select it, i notice almost immediately that the truck tends to surge almost like a lumpy idele except it only happens under light throttle in level six not five or lower. if i bury the pedal it goes away and goes like stink

also it appears to run up against a fuel shut off when i lay down the hammer in level six at around 2200 - 2500 rpm..

any thoughts?

thanks

Probably draining the rail. I would say that the loping at idle is just one of those things you'll have to deal with. Time for some more mods! The boxes can't do it all! LOL
