erm...i've been searching tyre for my car for sometime ady... dunno which good...currently is 195/50/15... but i wanna get 205/50/15 which is damn hard to get ^^" hopefully can perform on dry and can drive around...
cut it short,let's say i upgrade to a bigger injector,and there's a show of lean fuel.by avoiding using supplementary injector,just using bigger cc injector,let's say 750 or 1000cc injector, do i still need to...
