Well, This vvv

Less timing, richer commanded A/F for a wet kit. Less timing and ALL additional fuel added through the tune for a dry kit.
And also these cars have a lot of TQ management and DBW "gremlins" that have more control of the throttle than your right foot. These must be turned off(or values raised to where it won't activate).

Isnt the fueling ramped up when you within your window switch?
In mine(Dry) the A/F is "commanded"@10.25:1 above 2500rpm, additional fuel is added @ 3500(where I spray) so the O2's don't see a lean spike and use fuel trims to add fuel. I've never "data logged" nitrous tune "bottle off" but above 3500 it should/would be removing fuel in trims. On wet, it'll be about the same richer commanded A/F(mine super rich but that's how I like it) but the "kit" adds fuel when spraying and the "trims" will be adding it if running "bottle off" on N2O tune.
