Hello all its my 1st post!
Bought my psd about 3 months ago. Ran pretty darn good when I took it for a test drive, got a great deal on it so i went for it. 2 weeks ago I installed a boost gauge on it and noticed I was only able to get to 8psi. Turbo sounds a little weak <not bad but not like most psd`s I hear>. Took off the air intake hose and all the compressor fins look perfect, hardly no shaft play, and even at idel she spins fast. Ran throught the parking lot with the intake hose off and a conical filter just on the end of the turbo with no gain. It has already had a replaced exhaust on it, so I am kind of assuming its not the kat or muffler. I can hear the ebpv in the cold mornings and notice a decent increase when it opens so I am assuming it is not stuck shut.
Engine seems to be a little louder in the knock region then most the other psd`s I hear too. Did the 10k mod, no difference in feel, went to 22k and noticed a bit of an increase. Cannot get a single puff of black smoke out of her, and it feels the same at 1/4 throttle as 3/4 to full throttle.
I have a egt gauge, I just need some time to install it. Hopefully that will give me a little clue as to what is going on! I get no cel`s, and scanning shows not a single code stored.
I am a mechanic for uhaul, and have quite a bit of experience with the 7.3 idi, but never messed with a psd so I am kinda in the blue. Did a lot of reading and research before posting but never came up with anything conclusive from others yet.
Next step is to shim the fpr and put a gauge in there to see what my fuel pressure is, but before I get in the engine bay again, wondering if I should get a turbo to replace or not. Really don't have money to toss at that right now.
