Same for ecu tune, if manufacturer always knows better, why we ever do that?
Simply because manufacturer may have different priorities in mind (less repairs/longer life/play safer for misc potentially shitty fuels world-wide and so on).
Just like with tunes some customers may decide that OE safety margin is too big, they prioritise squeezing out every bit of performance out. To each his own.
As for me - i'm in the middle, not fully siding with any side. I'd love to see slight performance gains, yes. Goes along wish to lighten rest of drivetrain/rotational parts, like shaft/wheels/brakes to slightly up acceleration for this platform that seemingly has limit for na NA power. Also seen posts from engine builders/servicers about very quickly shot crank bearings on FA20/EJ20 where both LW FW & CP were used, but said that lightening just one by their book was fine. Hence if i'll ever decide on lightening pulleys/FW/CP, i'll listen to both sides and will act by advices from both of them.
