I think you could, just take the numbers the meter gives you with a grain
of salt!! I would try tuning to 12 or 12.5 with a (standard) UEGO
meter--just know that that's NOT really what you have with alky and nitrous
in the mix! 12.5 on a UEGO just means that you are about 25 to 30 % rich of
whatever stoich is for the particular fuel.
