Ka bogs when i go wot at idle

1992 nissan 240sx. I bought the car from some dumbass. I rebuilt the whole motor. New oversized pistons. New bearings rings. Headgaske. Headstuds. You get the general idea. I got the car running. It idle really smooth and revs decent when i give it light- halfway throttle. But when its idleing and
I give it to much gas it bogs bad. Timing is 20degress. Ecu has code 55(everything
Is in working order). I bypassed the knock sensor with a 550k resistor. Egr block off. Charcoal canister delete. Pair valve delete. Stock intake pipe with airfilter. 4-2-1 headers to a magnaflow muffler. What can make
It bog. It gets rather annoying.

you play around with the idle screw yet? when i rebuilt my motor it kind of idled low and when i would take off as soon as i pushed in the clutch it would die. played with the idle screw for about 30 min and that fixed it

maybe a dirty iavc ,aac, or both. might try cleaning them but that requires removing them. Also as a rule of thumb, removing the Egr and recirculation equipment will make the car run very rich. Had the same problem until i could get the ecu re-tuned.
