alvin24 said:dun waste money lar.. go get hotbits or powerzone extractor... better.. mivec is tuned for high revs... one which ur 4G91 will never be able to do... at least not until u get a set of high cams and rechip ur ECU to take out the rev cut.... other wise, its useless.
alvin.. how much does a hotbits xtractor cost, where 2 get them... thx
