I have 1997 F250HD with 340000 mi i had this truck since it was brand new. I want to restore the truck but first want to make sure motor rock solid. I’ve rebuilt the stock turbo and the EBV delete no change in power. Dropped the fuel tank found screen broken in pieces cleaned out fuel lines replaced screen currently have 60-65 psi at regulator, no big increase in power. Checked compression on cyl all 360 except #7 340 cold and 350 warm. So I had the stock injectors rebuilt to 160/0 and replaced all glow plugs and EOT sensor noticed a change in how fast it spools up little more power too. I pulled for the first time a small tractor hardly any power. I have a scan tool for iPhone no codes. Icp gets up to 2400-2500 wot , oh and blueish white smoke when rev high. Truck runs better once warmed up seems like. I live in Louisiana so no cold issues. Only sensors that have not been changed are the icp , IPR . Any ideas would be greatly appreciated.
