Speechless honestly! Props to the Creator and Developer of the apps. Very useful and helpful, the way diagram shown says it all. But, maybe english option is needed for our fellow tuner abroad. Kalau bisa ada opsi Bahasa Inggris, pengguna aplikasinya bisa lebih luas lagi. Saya akan selalu support karya anak bangsa. Thank you MotoRun team!
