@PuffwagonI took car to mechanic today to check out brake shudder problem, they took pads out and put an angled chamfer on the leading edge of the pad, it seems to have fixed it so that's cool.
Gone turbo side intake now and got 3582r with .70 front cover ramping in as hard as it can. 16-17 psi by 2500rpm 447rwkw on dynapack hub dyno which apparently read 10% high, so I have a genuine 400rwkw now.
