nitrous problem

Ok now we’re getting somewhere. If it’s rich it will just lay over and not gain rpm when you hit the button. If it’s not flowing nitrous your bottle pressure won’t change after a run. I would crack a nitrous line just before the solenoid and have someone crack open the bottle valve. Then verify clean voltage at the solenoid when activated. Then hook the whole system up and activate the nitrous side through the plate. If all looks good, put a new set of plugs in it and go test. I might drop a pound of fuel pressure from 9 to 8 as a test for the first run also.
