Nitrous Jetting

[exgmguy]

That is really the wrong way to do it. With nitrous you need less timing to make peak power. You don't need the distributor cranked like when it's N/A.

Also with that much extra fuel it will probably run so rich that it will slow down. I am guessing you don't want to mess with retarding timing on the street. Sometimes you want to run someone on motor only, and you don't want performance to suffer. No?
