Hmmmm sounds like your tuffet and valve seat. Minor lang po yan sir otomatic, wag lang po lalakas pa dun sa naririnig nyo and don't over rev your engine. :D

I use to have that sound in my D4BB engine, maingay nga po sya sa minor. Tatagal pa po yan by the time you decide to do with the engine. :D

With regards sa engine upgrade, not necessarily lalakas ang consumption, dipende po sa settings na balak ko sa engine nyo. :D
