No turbo pressure

Yesterday my truck made a loud noise that sounded like high air pressure Boom. I found one of the hoses going to the intercooler was busted. I replaced the hose but I still have 0 turbo boost. The truck was under full acceleration when it sounded off and fell flat on its face. I am running a performance upgrade on this truck from SuperChips. When this happened yesterday it started pouring white smoke out of the exhaust. I put it back to stock settings and it does not smoke as bad. Does this engine have a waste gate? If so where is it located. Does anyone have any idea what the heck happened?

Check the rubber boots..especially the one right at the turbo. That one usually fails on the underside where it can not be seen.
Also check for a split in the intercooler.

intercooler/boots bad some place, pressurize it with air and listen for leaks.

I replaced that hose yesterday and it was busted on the bottom. Does this engine have a waste gate or turbo bypass of any kind? Thanks for the help, I need it. HA HAAAA

the waste gate aint like a car turbo, you have a bostleak...look up a diy boost leak tester for diesel and make one and I think you'll find a crack/problem that way.

There are 2 of those boots...check the other one also.
No wastegate on a VGT turbo (that the 6.0 uses).
If you have the plastic pipe on the drivers side going from the intercooler to the intake elbow..check that for a split also.

I beleive nyc F-350 was the one that gave me this advice on turbo leaks- If you can go out in the cold and when its dark. Crawl up on the motor with a flash light and have some one fire up the motor. You will only have a short time so work fast but your gonna want to look for that vapor. Should be fairly easy to spot.
Ive tryed this a couple times and you it works very well.

Cant believe this just happened to someone else at the same time lol. I just had the same thing happen to me(completely stock 06 6.0). My boots are good but I did find 2 very small cracks on the lower underside of the plastic pipe, I believe these have been there since I bought the truck 1-1/2 years ago since its always been wet in that part of the engine compartment. Havent checked the intercooler itself yet but will do that tomorrow. Not sure if this is in relation but I've also been having a different problem with power/boost. Every once in a while when I drive my truck the boost will rise to 20 with rpms at 3000 but no acceleration with the pedal to the floor, then all the way to 30 and finally something clicks and the truck takes off then will quit accelerating after a few seconds and do the same thing. Any ideas? Also EGR is unplugged since its bad.

I cked both hoses and the plastic pipe also can not see any leaks in EGR intercooler. I can't hear any sounds coming from turbo, no whistle, whine, nothing. Engine still revs well but white smoke out the exhaust like the space shuttle taking off. Any ideas? also could the EGR be totally stopped up? Can I ck turbo by taking air intake off and visually ck turbo? Thanks for the help here because I am really lost on this one.

Just a thought, but did the intake hose blow off the elbow.
