Default H22 bogging cold start up?

Here goes nothing. I have a 4th gen prelude h22a swap chipped p28. The the issue im having is on cold start up, the engine bogs when giving it gas. After its warm, its drives fine below vtec, once i get to hi cam, you can feel and hear it activate but it bogs and sputters/hesitates. Its a major break up in in power. Im thinking, solving the bogging at cold start up, will also clear up my vtec sputtering issue. What could possibly be causing my issue?
New distributor
New injectors
Kemso 340 lph fuel pump
New fpr
New plugs
New wires
New etc sensor
New vtec solenoid gasket.
Pretty much all new since its a fresh build
Head is the newest with not even 50 since it was fully decarbonized with new seals, valves, springs, etc.
timing is good i set it up when motor was out of the car and spun it plenty of times and marks lined up. Im just stumped. Help???
