I just went through this and I know this is affecting other cars out there with 044 pumps going into the standard regulator you just don't know about it if pressures aren't checked.

We'll see what adam says when the dump goes on and we can get the full potential out of the motor and turbo Link to comment Share on other sites More sharing options...
