M2 & s_quilicot: I experienced chocking for a very short period lang when I engaged reverse (AT vehicle) backing up from our garage. But one thing's for sure, I really feel that my Altis became sluggish running on 93ron. It was way better running on xcs but I want to try Vpower next time. If it yields better FC, I'll stick with it.
Sluggish dahil retarded ang timing as a compensating ECU response to prevent pinging.

Dont put a joke in your million buck car. Teasing you car occasionally is
enough.
