dynoed with nitrous ??????????
when i dynoed with the nitrous on i made 403hp at 4300rpm and then it dropped to 358hp at 4400rpm.... then it pulled to 372hp at 5500rpm.....bottle pressure was at 1050psi before the run and it was 1000psi after the run..... so i know it was not the bottle pressure......the bottle only had 3 pounds in it but it still held pressure at 1000psi after the run.......could it be that my bottle was to low??? or could it be something else.... also when my power dropped the a/f got real fat..........thanks for any help

The bottle was low and during the dyno run the liquid nitrous in the bottle was probably sloshing around causing the rise an fall of hp. The pressure not dropping is most likely due to the bottle being warm.

h777 on your a/f - yes IMO 12.6 is to lean. 11.8-12.0 is better - better to safe than sorry.
On why your hp went down, it could be a couple of things. Did you A-tap it. Have you run it before the dyno - did it run good than. Only one way to find out on the nitrous is start with a full bottle. I am hoping you are actually tuning it, not just running it on the dyno. If the car is dumping extra fuel you could have other problems.
Wet or dry?
