Do I need to restore my factory tune to my truck before I replace the battery or will it keep the tune I have installed?

^X2 the tuner rewrites your PCM to replace the stock setting. So just like when you disconnect the battery with the stock tune it should keep your custom tune.

No problem, remember to follow the owners manual for allowing your truck to relearn its fuel idle and trim strategies as well as shift points again or it'll take longer and hinder your performance until it does relearn it.
