Just recently come home from Proton Service Cheras. Thank to Proton Staff there, very nice and helpful person.           Actually the problem is with computerize of the oil pedal. Just setting some configuration to the car, and nothing has been replaced. If any one feel lost of power (need to push to 3000-4000rpm to change gear - for Highline Auto), then it might be help for you to go SC and ask them to setting back. Thankfully no problem with engine or gear.
