Nitrous fuel pressue info needed

Have o2sensor have tuned with it in past.Somehow my local guru set me up with the motorcyle 6 cyl set up to get me to the lower 60 shot?? I will go with my gut feeling at local 1/8th track and think it will run sub 7,s.Nitrious is totally new to me And I dont know a thing about it..Then again 3 years ago I never even thought about just going down a dragstrip.That was stupid and too easy..go to line,wait for a green light and floor it.I learned very quickly there is more to it.Now I gotta learn how to lift or brake..I have had 4 car lenghts in the past and broken out.My foot doesnt listen to my brain when it tells it too lift.Mark
