So over the pond here in the US it is common for guys to do an AFM to MAF conversion or big six AFM conversion to eliminate the restriction caused by the AFM.
This works but to me it seems inefficient considering from what I understand the AFM measures pressure while a MAF measures mass. So it seems more efficient to use a MAP sensor.
Anyways I was wondering what the UK community tends to do to get rid the restriction caused by the AMF
AFM removal?

Can anyone suggest how to test if the boot lights are staying on with the boot shut?

It's not terribly easy to do that to a daily driver.

you can eliminate the AFM altogether and run Alpha-N with MAXX piggy back or Unichip-Q

I don't like how Alpha-N works.
Has anyone ever tried fitting a MAP sensor?
