Have a wilson direct port nitrous system, spraying a 250 shot with a 24 fuel jet. Cylinder 8 looks a little lean can i run a 25 fuel jet in that cylinder with out causing any problems? What is the aprox afr to 1 jet size change ? Thanks .mark

Yes thats the whole point of having a DP.

You can do it either way... add fuel or remove nitrous.
We always take nitrous out instead of adding fuel to a already HOT cyl.

If you have a 28n jet in back it down to 24 and make a run , check plugs.

I do have a 28 n jet and a 24f jet .so if i understand you correctly take the nitrous jet down to a 24 ? Isnt that a huge step ?

Depends on how lean it is.
28n is roughly 30hp .... 24n is roughly 22hp

We have one hole with 28n and took it down to 22n to get it right.

Number 8 seems to be that way.....
