fuel cut at 16psi

ok, i have been having fuel cut problems lately. my 1g mas is hacked and i have an safc unning like 15-17 psi. the problem is, at a certain rpm in 3rd gear and up i hit fuel cut. im thinking i dont have the maf hacked enough for the fuel compensation i have. i think its trickin the maf to think its flowing so much air that its not actually flowing, and the ecu thinks the maf is being over run. does this seem like a reason behind it because it never did it until i tuned my fuel trims in where i want them. any help?

Either, you have a boost leak, need to hack your MAS more, or need to take out more fuel with the S-AFC.
