im useing Apex i AFC Neo Fuel Management i checked fuel pressure today and it does not drop off at high rpm. (fp 50psi) i did find today that the boost goes from 17psi to 10psi when the problem happens so i think i am feeling a power loss. what could cause such a boost drop? it is a instintanious drop and comes right back. its like a switch. i can run 18psi in 1st and 2nd gear no prob. i think it has to do with holding boost for longer periods of time. thanks for any help you can provide.
