So after getting a Exedy Stage 2 clutch installed, we finally got our hands on the car again, and are really pleased with the result.
There is a good 20kw still to be had at the same high boost level but the 5PSI actuator, which is perfect for low boost, isn't holding boost at higher RPM's on high boost, and there is still some room for it to be leaned out - having said that, its probably a decent amount of torque already for the stock rods to handle.
The car is VERY quick on the street with all the torque where you need it - no need to wring its neck till redline to get any power, its all there where you need it and there is LOTS of it.
Really going to miss not driving this one!

After the first high boost run, the dyno owner said he thought that car was loosing traction so decided its best he sit on the back - it was a proud moment
