Injector troubles

[1gfromND]

K well heres the prob. I just completed putting my 550 RC's and now my car has kind of hesitation/rough feel after about 5k and all I've done so far is a mbc, 255 fuel pump, gauges boost, A/F, and volt and the A/F gauges says when I pin it it runs rich Like it should. Right now my boost is at 15 solid and before i put my injectors in it ran fine no problems at all but now it hesitates and what not. One thing i figured it might possibly be is knock so now im runnin 94 and it seemed to help but I still dont understand why with even more fuel available it acts like it almost fuel cuttin. Anyone wanna take a stab at this?

Its called too much fuel. You are way too rich, with no way to control the pump and injectors. Get an AFC and turn them down.

i agree that should fix all your problems. Hook up a data longer and check your O2's they will show how rich you are running.

dang, injectors and no form of fuel regulation. Get ur self an SAFC, they sell for way cheaper now that the SAFC-2's are around. or u can get the HKS AFR, or even the old school original AFC. Get sumthin on there man!!!!
