I have a blow off valve on my z31 and when i brake after a high rev it stalls out. Im assumeing its too rich from "discharging" metered air

is there a way to correct this? is it in the "TPMIN" or "TPMAX"?

any help will be much appricatied for myself as well as people down the road...

Theres the fuel cut/recover which should be the first thing to look at.

When your foot is off the acelerator at certain RPMs as in these tables it will cut the fuel until the recover point is reached. These are adjustable and also differ between auto/manual ECUs

The Total Theoretical Pulsewidth Min/Max are for limiting the minimum and maximum amount of fuel possibly injected. These are normally only changed when changing injector sizes
