First runs on Nitrous Out Direct Port Sys Got to make two passes. Both high 9s 143 and 145mph.
I'll post up some plugs in a little while for eval. This is scratching the surface. This DP system is really predictable. Best part is all of the cylinders got the same burn characteristic too.

Car is dialed at 200hp shot. Video camera goes to sleep in 4th gear, but the car was running hard.

Rich for my taste. Timing mark looks good but is relative to the combo. Try pulling some fuel as suggested and see if it picks up. I have been on both ends of the spectrum and sometimes more fuel is a good thing but in your case i would almost bet money it will go faster with a leaner condition.

Hopefully dialing the 250 and 300 shots won't take quite as long once I establish a base fuel pressure. I hope the gains are good and worth it with those.

don't pull fuel, its counter productive, your hp is actually in the fuel, the nitrous just lets you use more of it. Leaning out pulling fuel while maybe making more power is not growing at the rate your capable of. Up jet slowly till the tune up is right, then up jet square.
One thing you have to remember, as you grow into a 250-300 and plus shot car. Your time between refreshes falls. I don't know how much beyond 200 passes i'd go with out at least taking a look inside. point being, make use of your passes. Get after the tune up.

Its pretty rich right now a small change is not going to bring that around.
You need to pull timing also no matter which way you choose to lean it out.
What jets are in it? Fuel pressure?
Up jet square means when you find the right jetting for 200 you use the same spread when you go to 300.

Judging by the tracks you left in the video you may go quicker ET wise by jetting it down to 150-175HP, you are spinning the tire for a long ways down the track b ut it's moving good. I would get the traction down then jet the n2o up but it's your car have fun. You are making enough HP to run 9.00's if you could hook up what you have.
