Default upgrading injectors

hi everyone. currently running a ms1pnp on stock injectors which I think is 240cc injectors and looking to upgrade to 440cc.
my Required fuel is 13.2 on my stock injectors but
my question is if I fit 440cc injectors and reduce the required fuel down would the car run like normal? (ill do the calcs later) I don't fancy altering the VE tables

It should run close to normal. I'd say enough to get you buy, but you should still always tune ve.

If you don't want to alter your VE tables, then never make any modifications to your car again.

Problem solved!

going for twice the injector, simply because, is not an upgrade.

I'm turboing next month and ita getting mapped in February. I wanna be able to drive it to the rolling road to map it then. It's my daily runabout.
I just want it to be drivable for a week or so until it's properly mapped

okay that makes more sense.

you'll have to half the req_fuel and your accel enrichments (or any others not in % but total PW in ms).

there might be some fine tuning required in the fuel map just due to different charateristics but for the most part it shouldn't be an issue.
