I can assure you it's bad.
Don't get your hopes up to high about the fan delete mod.
It's nice to do when your fan clutch is broke, but otherwise please keep the money in your pocket.
Dyno tests I've seen have proven a 1~3bhp gain, so IMO it's not word the effort.

as for the pullies i dunno, ive yet to read any cautions where someone had damaged the car due to it.. ive talked to bmw about pullies, they obviously dont recommend them , but they do say there is a tolerance that most do follow, because most accesories do use more power than is required,
