Its been unplugged and no fuel system til this winter. I have a fuel pressure gauge ad it will sit at 68 idiling and wot it will drop to around 45 psi. It did that before this problem happened.
Is there another way to test the wastegate?

I'm thinking this could be the problem, I find it weird it won't push thru the brakes. I'm so lost with this problem I'm almost willing to try bubble gum and duct tape

What kind of tube do you have between the air filter and the turbo. Could it be collapsing, could your filter be collapsing?

It has a newer filter on it, but I'm waiting on my donaldson I ordered to get here. Th truck still does it without a filter. I have the 38r turbo so it has the boot it comes with. I tried putting a clamp around it forcing it to keep its shape and that didn't change a thing.
For the wastegate can I just plug the the end of it where the redline goes to see if that's the wastegate?

Remove the boot, filter and everything. Make sure there is nothing loose to get sucked into the turbo and see if it still does it.
like if you try a 'brake stand' it just flatlines the rpm, and won't break the tires loose?
that is a converter problem...

Well I'm glad to report my problem was solved. It was the garret boot going into my turbo. The boot was sucking the boot closed. If I would have thought of it when I would have checked that first as my first problem was because the filter got clogged. So it makes since it was that. Do any of you know where I can buy the boot? Thanks for the help guys.

Just get a hunk of 4" pipe and a donaldson filter and be done with it. Glad you found the problem.

dang man! how can one let a filter get that clogged to allow the turbo boot to collapse that much?

Being my truck spends a lot of time on dirt roads and it was an oiled filter. I assumed that being it wasonly 3 months old it wouldn't have been a problem. We discovered it was the problem when I took it off to clean it. I have had a k&n do the same thing happen a year or so ago. This one was a cheap one that I thought was similar to a 6637. I'm usually pretty good about maintence, and anyone who knows this is odd. I was looking at a buddys ats housing with the boot today, they put a ring around the center of the silicon boot. So I'm thinking this isn't the first time it happened.

regardless, dont you check your oil on a weekly basis and at the same time just maybe glance over at the filter?

Yes I do and when I get home today I will show what it looked like. After a 12hr day in the fields I was driving it home with a trailer and felt a loss in boost. It was a 3hr drive at night so when I stopped to fill up I looked over it all and couldn't see a problem. When I got home that next morning and pulled the filter to clean it. That's when I noticed it was clogged. I think in part the boots soft spot is right where my uppipes were leakin and there was soot all over it. The heat was another factor. I had my brother who has been wrenching for years look at it and you couldn't tell unless youflashed a light in it. It looked a like dusted but nothing major. The whole reason I replaced the last one is it looked clogged. I normally replace my filter every other oil change. This was my first experiance with an oiled filter. Like I said if you knew me you'd know this is an odd issue for me.
