Need a check on my Nitrous Barracuda setup

I tried the the setup I had, did 3 hits. One in 2nd gear and two in 3rd, seemed to do pretty good. Broke traction in second tho gonna need more tire.



Yeah I was a little worried with about the 93 octane, I wound up putting a can of that race gas octane booster in and it seemed to do good.



I have a photo of the plugs I have in there, I feel like they are non-projected. When I checked them right after the hits they had an orange coloration to them, except #8 and it looks like the one in the picture. I can't use leaded as I have O2 sensor would VP MS109 be good? I will work on the tune and bring the NOS on at 3800 seems like a small window (3800-6000)? and I will take closed loop to 12.8 AFR. Think I should tighten up the NOS AFR limit cuts to a more narrow band? Engine was built with NOS in mind, forged pistons,.030 ring gap and floating wrist pins.View attachment 1715758004


That plug is a projected tip. That’s what the Y stands for.
