BY THE WAY:
i was just reading about blow-off versus recirculators, the deal is that if you are using a MAF then you should "blow off" the pressure into the compressor inlet and before the MAF (recirculate). The deal here being that the ECU will flip out from the false signal it gets from the MAF when the charge air is blow into the atmosphere instead of into the compressor inlet (and thus passed the MAF). If you do vent to atmosphere a situation will occur that the ECU will make the A/F ratio too rich and bog down the hell out.
Long live WRC anti-lag systems & their descriptions!
