dsm injectors/ vafc tuning

i just installed dsm 450cc injectors on my ls/vtec.. i have a skunk2 ecu, skunk2 intake manifold. thats pretty much all the bolt ons i have.. my car idles like a big block with cams.. no matter what rpm i have the motor at, it does not have hardly any power...i know im running very rich and i need a vafc to control the air fuel.. but i have no idea how to tune my vafc.. if anyone has tuned theres after doing an install like this or just knows how to tune one, i would appreciate the help.. any comments or advice would be greatly appreciated.. thanx
