Good. But tell ur dad even if they replace a new car for u also go bring it to court. Don't be satisfied just because they replace a new car for u, or else their QC & PDI will NEVER improve and the way we look at Proton will stay the same. Dun just diam diam, u must know ur rights. The most Proton will do is replace a new engine for u. How much u wanna bet with me for that? They'll just swap a new engine for u & stamp it at JPJ, whereby this process will take up an entire month, maybe more. They'll bring out all sorts of bullsh!t telling u that they need the authorities to sign this & that, need to inspect, bla bla. Proton never take their customers seriously until they retaliate & complain. Time is gold, and if u had a dollar for every single second u wait for them to replace ur engine, u'll be a millionaire by the time u get ur car.
Press coverage? Good idea, but can be done only after u sue them. Or else Proton sue u back for defamation

Trust ur ears. If u think u hear loose noise, chances are they never tighten it properly. About the sluggish/underpowered part, u may wanna let ur ECU adapt itself for a few days to a week first before deciding to do anything else. Anything to do with electronics and sensors have to go through our ECU. So give it some time.
Urs is PE, rite? If they change ur sensor from 'VDO' to 'Made In China', it means all the PEs out there are running VDO Made In Germany stuff. C'mon, Continental is a Germany brand, of course must let it drink Hoeegarden la. If u let it drink chinese tea, how to expect it to perform?
What i'm trying to say is, what are the possibilities of an OEM sensor not working well with OEM ECU? And what are the chances of a 'China mali' brand working better with a German-engineered ECU?
Ermm...1stly,wat i change is only the crank sensor..if i am not mistaken,the base map and things which they learn earlier from my drving habit shoulf still be there rite due they didnt dc my batt and also reflash/reset(or wateva u uys call it)performance should not differs rite??
Yes mine is a PE la..
