This turbo will produce more power than a std 34/48 due to cutback blades which is why I have a touch more lag.
when is was on the dyno it was pressirising the cooling system due to a failed head gasket.
I knew this before the dyno due to cylinder leakage test which showed 60% on number 3 cylinder.
I have since done the gasket and still feels strong.
