They need to retain torque below 215nm to preserve CVT3 GB. But if you not sayang your GB you can increase the boost pressure more than 1 bar(Currently 0.6bar=8.70228psi) and remap ECU to release this real CFE performance.

Not sure about Preve, some said the one install on Exora is tuned more aggressive because of weight 1.5tan. I'm currently owner of exora CFE, no problem accelerate from 0 to 100 in 10 second. Preve should do better.

i think is the CVT ratio problem instead on engine

I just own a proton saga FLX SE recently compare with old avanza which i still drive i can fee the saga pick up which late respond compare regular AT. I can feel it need abt 1 or 2 second only can change  to ratio that match ur engine output if u maintain ur pedal with out press deeper.

I can feel the power but it like late coming only >< i guess there still need improve in tuning the CVT to math Malaysian drivestyle more

SE is 1.6

Maybe causes by safety feature on CVT3 GB. As inform by kristof (cvt supplier for proton) the clutch will half open for smooth acceleration from static and also to prevent engine die on low rpm until certain speed before clutch fully closed. You can refer here for CVT3 GB.

Mine is exora BOLD CFE currently 11-12L/100km. Still 3000KM.

SE is 1.6 but also might be their purpose to doing so also cause i heard Honda give up CVT on city because malaysian driver attitude on slam and drive which kill the CVT faster than  expected

That was very high for preve which weight around 1.3 tan compare with exora which 1.5 tan. What modification had you done? racing chip or only ECU remap?

city driving a lot?

than u will hard to archive 6.6 ><

City drive involve a lot stop and go which will drag FC to the worst

My avanza regular 60 highway 40 city give me 450km per tank but if i go in KL for whole day long >< which make it 50:50 my FC will drop till 380-400 per tank only

if u r 100% city drive definitely nothing strange to double up cause jamming also comsume Fuel too leh.... BTW also depend on driving attitude too la.. some ppl heavy foot one (like my boss my avanza if he drive sure can't archive 400km even highway lol

better comfort than my previous waja...my friends say backseat more spacious
