One problem that this model car has experienced is a plugged cat. This will slow the turbo by quite a bit. The only way I know to test the theory is to remove the V band clamp so there's a gap between the turbo exit and the pipe an drive it that way for a test run.

Yes it'll be kind of loud and soot up under the hood a little but if it goes like a scalded dog, there's your answer.

Also need to eliminate all the bubbles.
