I want to get a dry kit and a V-AFC. Possibility?
Would the V-AFC stop the nitrous from 'tricking' the fuel system? Would the nitrous override the V-AFC settings?

The nitrous does not need to trick the fuel system. And no, the nitrous would not override the V-AFC settings. The V-AFC is going to control how much the injectors spray...the nitrous will mix with fuel before that...they will act independantly.

it does seem as though it would conflict.. v-afc leaning out fuel coming in through the stock fuel system while the dry kit is adding fuel through the stock fuel system..

yes... I would like to know that also because I'm running dry system and I also currently have the VAFC which I set back to zero. So does anyone run VAFC with nitrous? I would like to know what your settings are.

First of all, we're talking about a wet system, not dry. On a dry setup, sure the V-AFC could affect the extra fuel that is needed but as long as you dyno-tune with the NOS you'll be just fine. It's all about tuning on the dyno woth a wideband O2 sensor.
