Found one somewhere near Summit Shopping Mall area. Mostly modify cars like Evo and Scooby. Owner has own Evo track car and few others. Next to it is also quite a reputable exhaust shop.
i heard from somewhere that when u install fuel management/piggyback to a VVT-i/DVVT engine, we must first diable them... if not, it will be quite hard to tune the fuel....
is that true?? i highly doubt dat la...but...
