I was reading a recent issue of scc(sport compact car) and they were comparing europes best(m3, s4, carrera 4s) against evo7's.. they tried to to dyno the m3 and they had a similar problem, but they said the cause was the car's speed sensors are on the front wheels and since the front wheels aren't moving it would engane a early revilimiter.. the crossfire will only rev to 4k in neutral i remember someone saying that, that might be the cause.. i'll try to find the the magazine so i can get more exact explanantion..

later..
