maybe we have to accept the fact that play turbo car must accept it high FC also.
for city drive n std boost, RM10 can get 40-50km is very good already.
i already accept it n dont care so much about it anymore. but anyway, this sat i plan to change my muffler from 2"(s-flow macro brand twin tail) to 3" inlet (tanabe G medalion). do u all think it will affect my FC? hehehehe...
