It's an 05 LLY. Banks is the worst company in the world to try to get ahold of.

Will it mess up the tunes in it? Just wanna make sure it won't hurt anything. It's my dads truck

i never had a problem flashing through my banks..

HOWEVER i would highly recommend removing it before adding another tune...i found out first hand that banks DOES make changes even while left on #1

Thanks Beech. I'm not adding another tune, just an update from the factory about idle, that has never been addressed.
