it depends on what things included like intercooler or ECU... if u want stage 1 running with intercooler it will be added up some amount from to that 1k by default (letsay it 1k, easy reference amount).. if u already have a way of remapping the stock ECU, so u dont need any piggyback... but when u want a PB ECU with fully mapped for Picanto (my ride mapping), so have to topup another amount though... so it is really depend on what u want... but actually, 1k is already with e-manage though...
and btw, yes, we r using garret...
