I have a 89 F350 7.3 idi with an unknown amount of miles, my guess is it rolled over twice so 214k miles. IP is definitely a replacement because it's not painted. Previous owners were crackheads so no info from them.
So I accelerate in third gear (ZF5), steady pressure on the pedal, and it hits 2300 and then acts like it hits boost. Revs up faster, sounds different and keeps going all the way up till 3400 when I shift, because i don't want to go any higher. Mind you I've not pressed more on the gas pedal. It doesn't do it as much in 4th, and not at all in 5th. Haven't tried 1st and 2nd. Has anyone else experienced this? I'm thinking the IP could be going bad, and I have a turbo idi IP ready to swap in if needed.
Also when downshifting or coming down from high RPM, it'll lunge forward, as if I tapped the gas quickly. I know it's not the clutch slipping as that's all brand new. So it's slowing down from 3000 rpm, and acts normally, then it jumps back up 100 more rpm, and continues acting normally. It'll do that only coming down from high rpm, and only like 3-4 times.
All sorts of weird things, I'm wondering if it's just the IP.
