i got my f22 running good allmotor. the afr is at 12.8 to 13.5 allmotor. when i spray just a 50 shot it will go below 10.0 afr. i dont have any detonation. can i rejet the fuel pressure jet to get my afr in the 11.5 to 12.5 range. because it sucks to have to tune the fuel with my crome just to spray, then go back to the allmotor tune.

so its a wet shot? title says dry.

I think he is referring to the bypass jet that comes with the dry kit.

I think going to a smaller bypass jet will lower the amount of fuel pressure at the rail, so the stock injectors will flow less fuel thus leaning out your motor.

You might need to buy several different jet sizes which could get expensive at around $7 a jet. But once done you should be good.
