720cc injectors, bolt on mod or do they require a ecu???
 

as the title says, if i want to put 720cc injors in my turbo do i just pull the old ones out and and put the new ones in any away i go??? of do i need a diff ecu or piggy back or chip or bla bla bla whatever??? thank you

Piggyback/Rtek/new ECU, otherwise you have no way to control how much fuel they spew.

To do it correctly you need one of the above. If you just throw them in you will run very pig rich.

But... with the amount of people here who likes flames.... this should give you some nice ones????
