Mr_4.0 Member 1,096 Member For: 13y 9m 21d Posted 13/05/13 07:55 AM Share Posted 13/05/13 07:55 AM Don't use an eboost if you don't need to. In this case, you don't need to. What cat? Have you taken out and checked it? Tried a different actuator? Checked inlet manifold for leaks? Checked there's no bolts missing around exhaust manifold or turbo?

I got a plazy 1200 cooler so im sure its not suffocating Link to comment Share on other sites More sharing options...

Swap it out for a 15+ Link to comment Share on other sites More sharing options...
