You could but that A/F isn't too bad for a mostly stock car. You might gain 10 HP by bumping up the gas a little, but a lean car makes more power, but you are a little too lean if you want to race it. Not sure what a TPI motor likes but I know that an LS1 likes about 12.5:1 air fuel (give or take a little). Either way an AFPR is a good investment.
