RE: 2350 fuel pressure decay Fault code 4726

Not surprised with this response on the program. The truck actually has 3.73 gears in the back. I’ve got maybe 7000km on the truck since it was programmed. Exhaust is completely straight piped, dpf and scr removed completely. I have driven the truck always above 1500rpm. Truck will sit until until I can get this resolved. I need to get in contact with someone on here that can help me get this right.
