Nah, some came with a little controller and you could change settings on the fly. The immediate benefit is better fuel economy on almost any mode. All it does is mess with the ecu within its limits. Doesn’t affect warranty and doesn’t cause any more wear.

I know GM and Toyota like to squirrel away a little extra fuel economy and a few extra HP because they don’t think you deserve it.
