Fuel cut question

[davidgt97]

Ok, I have been trying to figure out what causes my car to buck and hesitate at 4k. I have changed out most of what I could think of: plugs(gapped at 28), wires, o2. It still runs the same. I have also done several boost leak tests and I think I have them all fixed. It takes 1:50 for me to fully loose 20psi of boost during a boost leak test and this is true whether I do it at the turbo or the throttle body. I am wondering if this could be fuel cut but I've alrready read 50 posts this morning and it seems to me most people are as unsure about fuel cut as I am. So my question is what causes it. I have heard it is a certain voltage seen by the MAP and I've also heard it is an air volume seen by the MAF. Either way I should be able to monitor this w/ my data logger right? If I see either sensor try to go above what ever the limit is then this is whats causing the cut right?

Ok so fuel cut is caused by the MAF seeing an excessive volume of air. My data logger has the MAF sensor listed so I should be able to monitor it right? What is the magic # that causes the ecu to cut the juice?
