Dyno Tuned Today

I had my TRD-OR 6MT dyno tuned today by https://www.camtuningperformance.com/. Cam came over to the house on Saturday after a club breakfast, and did a minor tune on my truck. Today, he did his dyno tune. I was pleased after the minor tune he did on Saturday. I was super impressed driving home this afternoon after the dyno tune. I can't wait to get the truck on the road for another adventure. This was on 91 octane and 285/70 tires.

Hello,
I'm thinking about replacing the OE flooded lead acid battery with an equivalent size AGM type battery.
The Tacoma charging system provides 13.9 Volts to the stock OE battery.
An AGM battery typically needs 14.4-14.6 volts to properly charge.
Is the alternator/charging system voltage able to be changed/increased to allow for proper AGM charging?
Does anyone know what the procedure is? Is a dealer level Scan tool required to do this modification?
Thanks in advance.
