Was the map fooler installed prior to the codes or are you trying to use it as a part of the diagnostics?
If it was installed at the time the codes occurred, then take the map fooler out of the equation. Clear codes and see what codes return.
Without looking up codes, I believe P1740 is a transmission solenoid code. Torque converter solenoid. I think.
P013 doesn't sound correct, can you verify?
P0236, P0237, P0238 are MAP codes
What all is done to the truck that is not factory?
