I'm driving Civic 9gen, 2.0, just install the VS, my throttle response is much better now, low end throttle respond is awesome. I also notice that gear change is much better, I can use my normal 50%throttle to get higher speed (normally can get about 85-95km/hr, now can get about 105km/hr. What I can say it improve my car response, power feel the same, but car respond become sharp.

I never expect to get this improvement, my intention is just to improve my battery life span, as some of my friends mention that bigger capacity car (2 liter and above) won't feel much difference in performance after install the VS, but Eric product does have difference to my car. Now waiting to install the GC.
