Changing Injectors

[skybee 93]

how are ya lads,

im about to buy and install 550cc injectors. now ive been told two different things. im currently running 10psi high boost, when i put the new injectors in will i need the car tuned to suite. some people say nope the cpu will work out ratios and others say yes you should get it tuned. dont know?

I put Nismo 600's in my GTR and it died in the arse. Some PFC setting, meh could be different for every application.

you wont be able to use the injectors or "get it tuned" unless you have an aftermarket/remapped ECU or a piggyback ECU

as above, you need a programable ECU like a Power fc. Then you can set the injector trim, which will at least get you to the tuner.

Agreed.... Or just get the tuner to put the inj in and tune it straight after, but they wont work with standard ecu, it'll just over fuel and die on its arse as Topaz said.
