Is there a way to acquire the Hex Code from my '10 FX4 without using a programmer? I'm about to venture into the realm of custom tunes, and I believe this code to be of value to my potential programmer. How can I get it? On a scale of 1-10 how beneficial is this compared to just offering him the PCM code off the firewall sticker?

Still learning.... bear with me.

BTW, I have an OBDII code reader, that I got to remove trouble codes, and to turn off air bag lights, and tried it for kicks. Couldn't find anything in the manual, or in the tool menus to give me this info.
