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.

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.

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
