Carl you should be able to just have your LPM programmer leave the stock MAF
curve in the EEC, and your Pro M 77 should work fine.

Here's the stock chart if you like techie stuff :)  As far as I know, Pro M
is about the only company that will supply you with a chart of your meter as
it's calibrated (at least on their 77mm unit).  Nice for tuning if you are
using a non-stock curve.

Note you can set the max voltage in the EEC to 5 volt (assuming you have a
meter that will accurately measure at that high of voltage) but I still say
you are better off working on the other/middle end of the curve (ie, you
want some headroom)
