does any one know if there is a way to see if my truck every had a tuner or programmer at some point?

Check the engine hours and key cycles compared to how many miles are on it. I think it can only be done at the dealer. Or you can pull the heads and check for a nice star burn pattern on the cylinder.

ok thanks and what does a torque converter lock up switch do?

It burns up torque converters faster in these trucks. If you want a TC lock, get some tuning with it in the programming. Eric from Innovative has excellent transmission tuning as well as some of the best (if not the best) power tuning.
