When I bought the truck it had terrible throttle response, I mean like press the peddle and wait 5 seconds to hear it rev. A mechanic friend has rebuilt several injection pumps like mine before so I bought the kit and we rebuilt it. Now the thing revs fine, sounds fine, runs fine, as long as your on level ground or down hill. On even the slightest incline, it just looses power. You can be running 65 and it'll just go down until your to 30. I know these things aren't know for being powerful but come on... It's geared 4.56 with 35s. It just runs too good on level ground to make me believe there's nothing wrong with it. Checked the fuel pressure to the IP and it's getting around 5 psi idling and at wot, doesn't change, even on the hills where it looses power. Is it my IP? What else is there to check?
