Nitrous help

I use a holley black pump to feed engine and nitrous and Y off the fuel to another fuel pressure regulator and gauge for the nitrous under the hood. Fuel line is 3/8 steel that is dead headed. I set that up to free flow at I think 5lbs? I cant remember, have to look at my notes. Works good, I started with 100 shot and then a 150, just make sure to pull enough timming and sneak up on the tune. Helps keep your engine in one piece. I need a taller tire to get my rpm down at the track, was trapping at 6800-6900 rpm, about 800 more that NA, little more than I like but sure is fun.
