Savvy - Map Sensor or Air Flow Sensor

Guys.

Need help here. Is Proton Savvy using Map Sensor or Air Flow Sensor. I have this problem when the engine is cold. The idling isnt as normal, and when i drive it without proper warmup, it jerks.

This happens after i change the exhaust (only muffler). And later only when i change the air-intake.

I seriously have no idea why. Guys. please help me.

Thanks..
