2000 F350 7.3 Low Boost When Cold
This is pertaining to the truck in my sig - see my sig for mods and specs.
Whenever the truck is cold I cannot make boost. It seems as though the waste gate is open. You can hear what I would call a whooshing noise out the exhaust (cant hear any engine noise out of exhaust just sounds like a massive amount of air coming out the pipes). It will do this constantly until it reach almost operating temp. From that point until it reaches operating temp it will do it on and off... basically like an A/C compressor going on and off. If I try to drive the truck before it reaches operating temp I will make zero boost... but if I go to WOP (wide open throttle) it will come out of it, and when it does its instantly at about 20-23 psi and the truck just takes off like a bat out of hell. After the truck gets to operating temp it runs great no problems.
The only issues with the truck that I know of right now is that the intake air heater is bad and unhooked (it is still installed its just bad) and the injector in cyl 8 is leaking (not sure if its fuel or oil leaking but it failed an injector balance test on a solus).
Any help would be greatly appreciated!
Thanks in advance guys.
