I just bought the VS from brother Eric an hour ago & after he helped me to install it, here's what i noticed on the drive home :

1) Lights noticeably brighter (both headlights & cabin lights; was thinking of changing the bulbs this weekend but looks like i won't have to now )
2) Changing of gears smoother (i'm using auto and can feel the difference)
3) Audio's clarity greatly improved
4) Could feel power was constant and no disruptions

Btw, my car is a 2.0 so if this is what Eric's VS can do for it, imagine how much more improvement it can make for yours ...

Just a short note to add .... Eric is a very nice seller, up front and honest with his product. Although it's a DIY, but i believe the ingredients are of quality. And this time, i'm proud to say 'Belilah barangan buatan Malaysia'

I'm just a happy & satisfied customer who's gotten a good deal here on LY.net & will continue to monitor over the next few weeks and give my feedback.

2 thumbs up for Eric; you make us computer geeks/nerds out there proud
