As far as I know you have to use a tuner to change it or take it to a dealer.
There is no on board programming for it.
Most tuners will do it but even the cheap ones are a couple hundred dollars
Maybe who you purchased the trucks through can do it if they are the ones who set it

A tuner would fix the speedo problem too as you can adjust for different tire sizes.
Get a hold of hypertech and ask about the max energy 2.0 tuner and see if they will allow you to tune all 3 trucks since they are the same as a bulk package.

I believe when you hookup a new tuner it will see whatever tune is already on the truck and call it the original tune.
It will think it's the factory original tune. When you change the tune the tuner will save the old tune as the original.
If you want to use the tuner on a different truck you have to put the first truck back to the original tune to free it up.
Then there is the problem, what it thinks is an factory tune is not and your first truck will go back to the speed limiter settings that were on it you were trying to get rid of.

But if you contact a tuner rep and explain what you have they may work with you so you can get all 3 trucks reprogrammed under one license.

That could possibly be the cheaper route depending on the dealer charge.
If they would go $100.00 a truck that would equal the price of a cheaper tuner.
