What I'm looking for from the 3 thing is :

1. Performance/feature vs cost
2. At which point of your engine mod u should swith from stock->piggyback & piggyback->standalone
3. Maintain drivability (or close to driveable) for normal driving eg going to pasar, fetching awek, balik kampung etc :)

This is a difficult subject isn't it ;) From my understanding, u should only get a piggyback when you've do some mod that your stock ECU can no longer adjust, or when u changed your injectors or fuel pump. If piggyback also have run out out adjustment (piggyback can add upto 50% more fuel over stock ECU right?), only then go for standalone ECU. So do it according to your mods.
