TBH the Airia is mental, hitting wide open throttle is like flicking a switch into insanity. Even with timing and turbo turned right down.
Can get my 410 wheelying down the back straight. First time I tried anything extra (bit of timing) I snapped a tresrey half shaft.........
The black Diamond seems to be the same sort of thing.
(I'm comparing with a reventon pro, a gt2.0lpf and fusion exceed pro, all fairly decent kit)
I may even put a slower motor in.
