I had my 2001 3500 with Edge comp box an Smarty S03 stack. Always had smarty on lvl9 an comp box on 5x5. Loved it! Truck loved it! Had to remove vp44 to do the tappet cover gasket an damaged the vp44 case installing it back in. Took the pump in to get it fixed an figured to get it rebuilt while its out. An now its tripped some timming code an killd my new vp44 on same settings i had for years before on old pump. Any ideas why this combo would do this to new/rebuilt vp44. The shop that rebuilt it fixed the pump again under warranty an had no answers for me why it would do that. Just scared to do that setup again an have to go thru all that work again pulling pump.
