I have an 05 psd. It has ARP head studs, egr delete, SCT tunes. I just finished installing the stand pipes update, dummy plug update, STC fitting update, injector o'rings, ICP sensor, and the IPR valve in the High Pressure Oil System. Truck took a bit to crank up after breaking the HPO system apart like normal. It runs fine in park. Soon as you throw it in drive or reverse it vibrates like it wants to die. Really doesn't take the acceleration at all, if you get on the pedal it damn near dies and blows out an ungodly amount of straight black smoke. I'm not pulling any DTC's. I drove it around the neighborhood a couple of times and it never straightened out. I couldn't even make it up the smallest incline, like the driveway. I'm stumped. Any help I would sure appreciate it.
