So how do newer focus st's do it? They have torque limiter in 1st and 2nd.

I've read somewhere there is something that goes where reverse switch is on gearbox. If not d'ya think emerald could be mapped to limit boost below certain revs at lower speeds?

I have the speed sensor still attached to newer gearbox and don't need it for anything on car. Could have one map limit boost under certain speed and throttle position/revs.
