fuel pressure for nitrous...

i'm not real sure what you mean as I hadn't had any coffee yet. maybe a pic would do it. I'm sure 7lbs is too much for either the carb and the nos. run the carb at no more than 6lbs and the nos at 5-6lbs. you might consider upping the gas jet to around a 41 or 42. an eleven step difference seems kind of lean. are you flowing the gas through the jet? do you have two separate regulators? check out the pics, see how the nos has it's own regulators for each stage and the motor has it's own.
