Made 400rwhp (298rwkw) at 19 psi and 415rwhp (309rwkw) at 22 psi. Made 400rwhp by 4800rpm. Didn't bother turning it up more due to the stock head internals and restrictive air filter and exhaust. Full boost at about 3500rpm.
The air filter was almost sucking itself inside out. The cat and catback are probably a restriction too but in saying that the car is very quiet.
It is what it is. I'm not happy yet so better results yet to come
