Fuel cut diagnosis

[xdxoxuxgx]

I've been hitting fuel cut lately, and it's because for some reason, under WOT, I have to add 20% air from like 4k up on my AFC to obtain a safe A/F ratio (10/11:1) and I would assume that with the ECU reading all this extra air, I hit fuel cut. My brother suggested just getting a fuel cut defencer, but I would rather figure out why I have to add so much air. I have no knock either. I have a rewired 255HP, with an AFPR, and 560s. Any suggestions?

Have you done a BLT lately?

My friend is currently borrowing my boost leak tester, so unfortunately I can't do a test at the moment. I will definitely check that though, but it just doesn't seem like a boost like.

Thanks for that, that provided a lot of information. But I feel that I'm doing everything right to prevent fuel cut, so maybe it is just a boost leak. I have a 2g maf, but I have bigger injectors to counterbalance that, and an AFC to control them. I appreciate your help though, thanks.
