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

what is the current set-up on your VAFC on the wide and narrow throttle? Let me know.......

if it's stock, meaning at 0 for high and low throttle he probably needs to drop it. if you have a air fuel ratio guage, tune your afc to the aif fuel ratio guage. that's what i had to do.

whoops, said that messed up. if his wide and narrow throttle is set at 0 all around he probably needs to drop it. he's n/a so he's probably gonna have to go lower than the hack.
