New OEM HFCM, new OEM fuel regulator kit, 155/30 premiums on a stock tune won’t hold PSI at WOT. I’ve said it a million times at the very least 155/30’s needs a healthy stock pump AND at minimum a regulated return anything else above that has to have a full fuel system. This truck came in on roll back wouldn’t even run. It had new “oem” injectors installed in February of this year and customer didn’t even make it home before the truck shut off and left him stranded. It sat until it came here. Did some diag , thru the fuel psi kit on wasn’t making any pressure with the brand new HFCM the last shop installed. Quick observation didn’t appear fuel regulator had been touched. Easy enough installed a FoMoCo kit truck fired right up but ran horrible, no power, miss firing on all cylinders. All it needed was proper Diag and then a second set of sticks because the brand new stocks were smoked. Previous shop also stated it needed headgaskets that was the reason it died. Lmao not the case. Now just gotta get the fuel system upgraded and send her down the road.
