nitrous power down?

Have a Nitrous Works wet system that I've used on my stock LT1 with no problems. BBk headers, cutout MSD ignition 6al,CAI all the little goodies. Have now rebuilt the engine into an 383, with the LT4 Hotcam. 30 lb injectors SVO. roller rockers, headers and everything that was there before. The car ran well, and I am happy with it. We opened the bottle with a 125 shot, and made an high 11 pass. We left and when I got home I looked up the power on prestage dot com. Supposedly instead of a 125 shot to run the number, we were only getting an 80 shot. Any ideas?

what was bottle pressure? weather? how did the car run n/a?

now,are you sure it isnt to fat with the new injectors? what about plugs,did you read them after the run?
