If your wondering about the trap ox on an 85 Kali, it sits between the exhaust manifold and the turbo. Since you mentioned the U tube it probably doesn't have the trap ox on it any more. You might need a new wastegate spring, my 85 Kalifornistani 300SD does.

How are you testing your boost? (flooring it, dirving up a steep hill, power braking it, etc...)
