WHAT IS FUEL CUT?
Fuel cut is actually a removal of the the injector firing signal from the ECU. This is to say that your engine computer doesn't put fuel in the engine, hence the name.
WHAT CAUSES FUEL CUT?
Despite the rumors of fuel cut being caused by too low of fuel pressure, too small of injectors, high flowing exhaust, high flowing intake, or large turbos fuel cut is not directly caused by any of these. Fuel cut is actually caused by the ECU seeing more air entering the engine than it was originally programmed to use. This likely cooresponds with an injector duty cycle which is unsafe or unattainable. So basically fuel cut is caused by the MAF seeing too much air. Don't ask what too much air is....
WHY DO WE GET FUEL CUT?
Since fuel cut is caused by the ECU seeing too much air we get fuel cut by increasing the air flow through the MAF.
WHAT CAUSES TOO MUCH AIR TO BE SEEN BY THE MAF?
Many things can cause this. basically anything you do to the engine to make more power increases the airflow...way to many to list here.
