Default P0101 and P0448 - 06-29-2020, 07:50 PM

One day after JB4 install and using Map6 on Texas 93 pump gas, these codes showed up. A search here shows other have had it but didn't show any resolution. 0101 is a MAF and 0448 is Evap Emission Vent Control Shorted Circuit.
Anyone else have history of this?

Clear all ign on, engine off, and see what comes back up. MAF code could be a loose connection on the JB4 to the map sensor or an issue with the MAF sensor if an intake is installed.
