I have a 1g dsm 5spd why does it seem like its fuel cutting?

My mods are mhi 16g from forced performance,walbro 190 rewired, hallman boost controller, autometer boost gauge.....I am running 10-12 psi and at 4500 rpm it fuel cuts and it seems like it shouldn't be for the amount of boost I am pushing...I have ran out of ideas I didn't think I would need to get bigger injectors and afc yet but maybe I do....please help!! Thanks,tyler

    Don't use afcs. If you can't shell out for a real tuning solution, you shouldn't be toying around with your car. You need to figure out what your AFRs are. Get a wideband and see if you're leaning out. 16gs are usually good up to about 16lbs before you start getting into trouble but you're lacking a lot of the supporting mods you should have already had before you started upgrading your turbo.
