Swapped out my destroyed up-pipe and did a top job.
Realised JUST how much it was leaking when I pulled out of the industrial estate. Ride feels so much better, it's so much more responsive, all of that awful turbo lag is gone, hitting full boost much easier, and even at low rev's the turbo and induction system are making some lovely little noises!
Now i have all of my power back and looking forward to seeing what sort of power it is exactly on the rollers this month :-D
Engine is back to being very quiet again instead of sounding like some sort of 1920's agricultural machine
Very pleased...thanks boss!!
