anyone try this product before ?
since my place don't have people do reflash or tune or anything...
so is this a good idea ?
i heard good and bad thing for this...
anyone used it before ?
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...
