Hi Heng,
I have installed the single Surbo in my Atos (without purge line stopper) and the performance of my little Atos has improved. I'm quite surprised a little air gadget like Surbo can make the car more responsive. This afternoon, my mechanic used the Hi-Scan to diagnose the engine and eveything's running fine. No trouble codes.

Surbo Engineering's comment: the purge can be stopped as an option if you ever feel the pressure escaping. As long as the purge switch is never pulled off, stopping the line physically by rubber plugs will not be detectable, unless there is a leak in the Surbo system.
Watch the video above showing how an engine revs with Surbo. Or watch it with the How it works page.

More torque and BHP (dyno test)
Quick revving (1/2 throttle to RPM limit)
