Just started my truck tonight after ARP studs, dummy plugs, stand pipes, stc, water pump, rodded radiator, heater core, BPD egr cooler, new oil cooler, cleaned exhaust side of turbo, new batteries, blue spring upgrade, re-ringed injectors, new glow plug harnesses, all new hoses(heater and radiator), I am sure I am missing something. After all of that I have a whistle (or whine) coming from the turbo area. Can't quite pin point it. What do you all think it could be. Thanks in advance.
That's what I was thinking. Will have to check it out after work tomorrow. Although the truck seems to run smoother and have more get up and go. Also is there any reason to do a turbo re-learn? I did not disassemble the entire unit.
