No because you won't be getting the quantity of hot exhaust gasses needed to spool the snail up, hence the r****d and burning it in the manifold instead to produce the desired effect.Surely if the throttle is wide open but the revs are being held back by ignition cuts (like a launch control system can) it would start to produce boost?? I maybe wrong as Ive never owned a car with either.
Jap crap.
