sounds like a tractor
lifters are very noisy on your car.
here is the thing. Over boosting with an mbc is NOT good. did you try another MBC?
If you did and this MBC works fine on another car and is set to 22psi and you still boosting higher you have wastegate problems.
You have to test your wastegate lines and test the wastgate themselves. Put pressure just to the wastegate lines, get a dude under the car and see if they open at the same time and close at the same time. Its going to be hard to get an acurate reading doing this with the turbos in the car but at least try.
Also its important to know at what pressure are they opening. Any higher than 7psi you have a problem.

havent tested another MBC...
but vast said there is a very good possiblity that i have a boost leak, tried to hook a pressure tester up, and didnt get enough pressure...so im hoping that the hole on the brake booster line, could be the boost leak making me over work my turbos...and about the lifters, what can i do about that???
car is going to induktion march 19th...can i just tape up the hole on my brake booster line till then???? and ill let them check my boost issues??? unless i can pressure test before i take the car in..
