Pull your air inlet tube off the front of your turbo and see if the comp wheel is turning while the engine is idling. If it is turning VERY slow than it's time for a new turbo or rebuild. Also where is your PSI reading coming from? Could be a leaky gasket, boot or IC.

I ended up finding out my wastegate was stuck open, finally after a couple days of wrenching. It wasn't open much but apparently is doesn't take much. I thank you both for your prompt replies! Hope to see you at a future meet!!

That was also one of my guess but you said you had the waste gate plugged so I figured you already went over that. Glad to see it's fixed and thanks kscumminsdriver.:thumbsup:

I had it plugged but the spring in the actuator was broken aparently and would let the waste gate open under idle pressure even. It took me a bit to figure out that the waste gate actuator itself wasn't able to hold the waste gate shut even unplugged.

if you ever need any help im back in the wonderfull wichititty and know a thing or two about these piles lol. we need to get a wichita meet and greet set up (or some where else)

You know I might take ya up on that some time. I would like to make sure that everything on my truck is up to par. I do not know if I am getting all the grunt out of this old beast that I can or if I have something else holding me back on it.

well we can bump the timing mod the afc and a few other things, i got a friends truck from a 17.7 1/4 to a 15.5 in denver lol. it was good times

That sounds like fun, I wanted to know how to bump the timing but didn't want to attempt it without knowing what I am doing. I think I should get a 100 plate for it, that should be a bigger step up in the power department.
