Nitrous plumbing A1A...??..

Since it's a 4-speed I'll likely do little 3 second blast between gears and I do have a low pressure switch that will cut the whole system off if it goes under 5 lb....

Be smart and good news on the LP switch!

Like said before I ran 2 stage one carb, one on throttle and #Two on a shifter button. Your setup is all in both plates it seems. It is like 2 stages at once. Doubles the trouble if not right!
