me and my brother have been building his da for the past few years here and there.the plan was to build and boost the car but he stopped working on it due to having a kid due any day now and as a surprise i am trying to get it running perfect for him just na for now

the problem-
the car will only idle with the trottle cracked slightly,when i go to rev it up it delays then revs up. if i give it constant throttle for example i hold it at 2k rpms it pops and seems to bogg and backfire. i am pretty sure its running to rich seeing as how i saw a flame shoot out the header,but im not quite sure y unless its my fuel pump being to large.i know the fuel pump says operating psi is 72.5 but i figured the regulator would be able to control it but i may be wrong. i tired running a stock map sensor but didnt change,ive messed with fuel pressure going from 40 all the way to 60 any input would be greatly appreciated. this is my first k swap car ive done if anyone could tell me how to upload a video i took a qick video of the car running.
