Holley HP Steet wideband tuning

[Pyrotechnic]

I finally got my wideband oxygen sensor installed in my truck. The motor is 383 and the carb is a Holley HP Street 750CFM mechanical secondary.

As I expected by the smell of the exhaust, the truck runs has an AFR of about 12 at cruise anywhere between 30 and 65 MPH. However, when I accelerate to load the motor some to see how it runs when on the power valve, I get an AFR reading of around 14.

Is there something wrong here? Being that it is a double pumper I thought it would be rich all the time. I knew I would probably have to drill out the PVCR's after leaning out cruise AFR but right now it looks like they already need an increase.
