Mechanically, I don't know if it's correct. The fact that it's noisier doesn't mean that it's working better or worse.

If we assume he's correct, I go with the additive. For me, there is no kind of driving that I do that I need some incremental level of performance as a tradeoff for noise.

I could get a locker for my F-150 too, but the noise and feel for what is mostly highway driving is not worth the tradeoff.
