Adjust the low end VE map this should sort out the afr at idle

Yes, pull the numbers down this will reduce the afr.
Also if you are running a coil on plug kit make sure the dwell times are correct as this also messes up the idle afr

dont know if it is worth mentioning but. as the car warms up is when it seems to do worse at idle. i start with around -8 vacuum and and up around -11,-12 and thats when the idle goes rich

You'll be outflowing the FPR.

You'll know this once you measure fuel pressure.

It's a universal problem with bigger pumps and injectors.

But it won't be the only problem, it never is.
