OK great did you jet up the kit from what the manufacturer suggested. My engine runs great on motor but built it for spray , and now have finally got around to installing the plate.

granted, i run it mixed with 91 not straight. 2 ounces of marvel mystery oil for 5 gallons of fuel
Though i usually run 110 straight on the bottle i have ran the 91/av mix multiple times

I am jetted .063n/.055f for a 150 shot on a cheater plate.
On the 110 i dont back any timing out, on the av/91 i back 6 degrees out to be safe

Stick with NX's jetting they are really close. Run it, check the plugs and go from there

What HP of nitrous are you gonna run???
-
And the tune up chart Steve posted looks good. I'd do the 5psi fuel presure, 950 psi nitrous billet presure, 88 nos jet and 78 fuel jet, and retard 10 degrees of timing. You should gain 800 Rpm's on your tach.
-
Opps. Nitrous bottle presure
-
Going to work my way up to 250hp
-
Well follow that chart, always pull 2 degrees of timing per 50 hp of nitrous you turn on. Make sure you have 5 psi FLOWING fuel presure and bottle presure is important also. 950 psi is perfect.

What onthenos said. The biggest thing is flowing fuel psi
I can get you a picture of what I made up. It works for me
