I have a 88 supra "7mge" that i put a turbo on.

it has:
t3/t4 turbo intercooled
550 venom injectors
255 walboro fuel pump
fuel pres regulator
manual boost controler
50mm waste gate
headers 3" exhaust
hks headgasket an studs

so the problem is its running way to rich, i'm told that the only way to fix this problem is to put in an aem stand alone engine management system. i was wondering if there is any other cheaper way to fix this problem.. thank's for the help on this
