Just back from installing the Eco VS and also a testing of the PBTE device, test drive on a highway. I'm quite impressed especially when the price is not very expensive.

The Eco VS made my car feel smoother when picking up and the air-cond remains cool most of the time (meaning the compressor cuts off less). Other difference will have to drive for longer term only will be able to feel, also not to forget that my Vios is still quite new, not 1 year old yet.

The PBTE is also a good product, can feel the difference when tested side-by-side with my Panther. However, as my Panther is still quite new, I did not purchase the PBTE yet, will definitely consider it in the future, maybe when my Panther is over a year old.

Thumbs up for the product(s)!

Just noticed that you now only advertise your chasis foam and the PBTE on your signature, not focusing on the Eco VS?

Just upgraded my older Eco VS to the latest circuit earlier. Acceleration does seem to be more refined/steady, less spikes in power (basically effects are the same as the previous circuit, just even better now). Also tested to put 2 VS at a time to see the outcome and there was improvement but not by much so I conclude that 1 is more than enough.
