I sprayed a 125 wet shot to start out with tonight. I've got the nitrous coming in at 3500 rpm. When the nitrous hits it falls on it's face bad then it takes off. What could be causing this? BR6EF's are gapped at .038. A/F is a little lean. It's an NOS wet plate kit. Bottle pressure was 900 psi.
It almost sounds like its dumping fuel right before the nitrous hits.

Yeah that sounds like a possibility. I'm new to nitrous what could cause that to happen?
Could be different things. Difference in line length from solenoid to nozzle, not sure if you're running a purge or not, but that could be a cause. I'd imagine that at 900-1000 psi, that nitrous is moving much quicker than the fuel though.
I don't have a purge kit yet. I didn't measure but it looks like both the lines are about the same length.
Been doing some research. I have an NOS tps/window switch. One guy was saying he had the same problem when the tps was hooked up to the wire near the tb. When he hooked it up to a wire down by the pedal it fixed everything. I currently have mine hooked up to the green wire by the tb which gives a solid 4.1v. Nitrous activation is set at 3.9v
