I've just checked that my spare tyre is actually smaller than my original tyre. The spare tyre is 13" while my tyre is 15" size. Is it ok to use it or I need to replace it with the same size?
Hello all sifu out there. I have one question, should I get a Power FC ECU to fine tune the engine, do I still need a boost controller to adjust higher boost or the power FC can do everything?
