A/F ratio?

[Guero]

what should my a/f ratio be at with the kit and the N2O?

 

[Grn92LX]

12.8-13.0 n/a and i'd say in the high 11's on spray. Be sure to back the timing down on the n2o and that you have a good fuel pump. I like 255 high pressure pumps.

yeah i got the 255 pump, ill make sure ill be in the 11.'s when spraying, but how do you change it? and whats the best gauge for this?

Fuel pressure gauge or wideband unit?

You can change your a/f on the nitrous by playing with jetting. Also different nitrous pressures will change the a/f. Higher psi will be leaner than lower psi with the same jetting.
