map sensor and boost gauge disagree

my map sensor reads .80kg/cm2 when my boost gauge reads 10psi

how can I correct this?

which is more probable to be correct?

This is one of those notorious Power FC issues but to be sure you should test the gauge and commander outputs separately using a mityvac or equivalent. At .8kg/cm2 you should be showing 11.38 psi.

It's odd that your Power FC is showing higher boost than your gauge. It's the other way around for most of us.

Do not go with the PFC boost reading or your gauge.

Both are wrong.

The PFC has been proven wrong by many knowledgeable people. I have posted documented proof about this on this forum. Do a search.
