Phew finally got the exhuast leak fixed and check dis out, they said it was leaking from the turbo end and they had to drop the engine+box to get to it. The cars so much more perkier down bottom and bov sounds alot sharper also.

Now about boost, ive got a blitz nur exhaust but without the front pipe and ive got no cat, running twin apexi filters, greddy elbow, apexi 1st gen bst controller and HKS gen3 ssqv. What should be the max boost i could run reliably? Help? the cars done 77,000kms smokes a wee bit on boost black smoke that is.
