I suggest you buy a Wideband for your personal use. Im hoping the dyno wideband was broke because 14.8 AFR is motor blowing lean. And yea you should be putting down over 300whp @ 14psi. I know i did with a slipping clutch. You may want to think of a retune if the new wideband reads really lean too.
