Turbo is all on. Runs well - no surge.

No leaks or anything - the only thing is as soon as you shut off the car and put your head near the turbo you can hear sort of air or water moving. Can anybody else hear this. I didnt notice with the last turbo but I may not have paid that much attention.

From 4000-7000rpm is really strong. I'm only running about 9psi though. Slightly laggier but not much. Might be good for traction as it doen't seem to snap on boost quite as sharply as stock turbo. Running without a tune so really rich. Maybe with some tuning and more boost it will be good

In regards to the bubbling sound:

Did you bleed your cooling system? Are you sure you bled it properly? From the bolt on the plenum?

didnt get the noise then - maybe all the extra air has come out.

Birnie. I think it supplies lower voltage to the fuel pump at idle..
