Lol...very well could be a placebo effect but it is extremely noticeable even after 3k miles.
Here's my theory:
The stickier fluid with extra additives is allowing the pinion gears to more freely spin. Therefor when power is applied it gives the feel in the drivers seat of improved acceleration because throttle lag has been reduced drastically. Sport mode heavy acceleration truly pushes you back in the seat now.
Like I said...that's my theory, so I could be wrong but it seems plausible. Either way, I am glad I made the fluid switch.
