I just sent my car for servicing at this workshop @ Sin Ming. Told the boss abt the issues in my car. He suggested retuning my ECU for me. He said he can only do that when my engine has totally cool down. After retuning, my car's pick up is very smooth now. Power is also back when stopping at sloped junctions

. Strange thing is, i sent my car for retuning of ECU at TCM before but I didn't see such improvement back then

The boss also did some adjustment to the fuel filter coz I told him the fuel meter won't go to full after pumping full tank (he mentioned something about adjusting the needle or something like that). Now, my fuel meter is back to normal I think

Will pump another full tank to observe and see. the boss did say that the fuel filter has to be changed, although he suggested changing it after another 20000 - 30000km.
