Do you notice a loss in power and A Lot of black smoke?? IF not I would check the boost gauge and line goin to the gauge for leaks.

Check the rubber boots that connect the tubing from the Turbo to the intercooler, and the intercooler to the intake horn.
One might have popped off.
A simple hose clamp connection.

To prevent this in the future, clean both surfaces well, spary a little hairspray on the surfaces and secure them.
The hairspray will kinda help 'glue' the two together.

I cant seem to find a hole or anything and the hoses are still on but Im gonna look at them more tomorrow in the day light. is there any other sugestions???

Make sure the turbo is spinning freely.

I took the hose off from the turbo to the intercooler and found a crack but it wasnt all the way through and the cable thats on the turbo idk what it is but it was loose so I tightened it up and still nothin. The turbo is spinning but it is real loud whistling and whining noise.

can you build something to pressurize the hose at the turbo towards the engine..
you might find this crack is leaking air under pressure.
