AG audio is good.I have been his customer for a few years now and for my previous cars.He knows his stuff and he does not push you into buying anything.He explains it and then it is up to you to choose.Nice friendly chap.Look for Ah Guan.Cheers!
Recently installed SAFC in Wira 4G93 engine, but CheckEngine light turns on. RPM indicated only about half of the actual RPM meter reading, and no effect in A/F setting. Plug the whole SAFC to another car with 4G93...
