ya I apologize, thats what I meant (Fuel not boost)... same reason an HKS FCD is used to rid of that.jeffsti said:No such thing as BOOST CUT.
FUEL CUT happens when the ECU sees too much air through the air-flow meter. This is a safety feature that the ECU has from damaging your engine from a lean condition caused by excessive boost.
An intake and BOV will not cause boost the rise to the point of fuel cut. But it can happen even on a stock vehicle if for some reason the wastegate malfuctions and stays shut too long. When you add a boost controller, then you may run into fuel cut if you set the boost too high. The PSI fuel cut activates is dependent on many things, including air temperature.
The stock valve recirculates the air post- mass airflow meter, if you use a BOV, this air is released from the system. The ECM makes fuel calculations based on the air seen through the airflow meter. Therefore, you might (probably will) run rich for a split second when the BOV is blowing off air.ss3homer said:why shouldnt you get a bov though???
