Do you have excessively large brakes? It's a BMW, I would assume so, +100 (in your face!)... so 2350.
Could there be a torque adder? maybe, if so then add another +100 (in your face... maybe)... so 2450
IIRC the process weight is on crank hp, so you don't include the 0.82
so... maybe:
170 * 1.30 (BMW IT gains) = 221 * 12.9 lbs/hp (ITS multipler) = 2850 + 50 brakes + 50 torques + 50 wishbones? = 3000
