I'm not sure whether to reply in harsh manner or sarcastic manner. But the truth is:

You shouldn't modify anything related to the engine for a merely 1month old Proton Saga FL. If you buy a Proton you should be more aware about the warranty. What happens if your car breakdown when your warranty is already void? 3 years warranty went down the drain already.

Lack of power? No pickup? Perhaps you expected too much from a 1.3L sedan.
