by upgrading ecu without changing any other things wont give u significant performance upgrade... max also about 3-4bhp increase....

do up ur intake and exhaust first... den bigger injectors, ecu upgrade (piggyback or standalone) and so on... this will give u some improvement...

korekt korekt, piggyback or standalone will perform better with mods in other areas...

with bigger injectors ngam put bigger throttle body too, more fuel, more air
