Ah yes the ongoing discussion abut Singh grooves...

Not a new topic as you probably know already.

So far as I can find there has been NO independent testing or back to back tests either but a lot of discussion and much of it very heated.

The logic is doubtful and the OEM makers have dyno cells too these days so IF it was effective then SOMEONE (Ford , GM , Toyota or whoever) would have paid the licence fees and got ahead of the opposition.

Just my observations.
