I seen that the new ones work on LB7 & LLY, my buddy just bought a 05.
Anyways I was wondering if I could use it to remove the limiters & adjust for wheel size & let him run the performance program?

Programmers can only be used on one truck at a time, regardless of what options you choose.

I didn't know if it was a seperate thing or all on one. I haven't used a programmer with all the options.

Ya I know it was a dumbass question, figured I'd ask anyways.

It NEVER hurts to ask.
