You'll need a piggyback if you plan on using bigger injectors.
do i need one if i just plan on using stock injectors with fmu and fuel pump?

If you have a similar setup to the RRM kit, you shouldn't need a piggyback since the FMU will be doing the fuel "tuning" for you.
yeah thats what i thought, so getting that out of the way will save me some money.
as soon as you boost you should tune. and forget the piggyback and use ecuflash and evoscan. its cheaper
