Good evening guys,
Can anyone recommend a reputable firm to re-flow my 440cc side feed injectors up to 550's?
Thanks,
Andy.

Sorry, I should have said that my 440's are phase 1 or 1.5 and having been on laterals website they can't do these. They can only do phase 2 onwards.
Cheers,
Andy.

If lateral can't do it I would say maybe it can't be done. For example the yellow 440's can only be flowed to circa 900 not a specific amount like 550. This is too high for some applications. Also note some mappers are fussy about what injectors they will map...

Any downsides to big injectors

if they are too big you will get a rough and lumpy idle. If you only need to go from 440 to 500ish what about throwing in a fuel pressure regulator to get a little bump?

A little too big is ok. But if you need 550's 900-950 is far too much. Also taker seriously what I said about mapping. No point fitting something your mapper then says he can't map well.
