Normal for VE Table to exceed 100%? I added headers and a Balckwing . Went through it and did a VE/MAF tune. Some of the cells were in excess of 100%, (max 107%) @ 4400 and higher map readings.
In comparing my VE table with 2 other VE tables with headers/h/c, I noticed their VE tables topped out around 99%.
Questions is: Is it normal for modified motor to achieve >100% in VE tables?

I believe that just compares it to a number that you set up. So it would be possible but probably bad practice. The exact thing you are talking about is why I liked how LS1 Edit did their VE. Easier to think in the numbers and units you are actually working in.

This is because the other guy could have his IFR rate set differently than yours.

AFR WB was no richer than 12.6:1 and no leaner than 12.9:1.
FWIW, When I started to do my VE tune, the car went into limp home mode. I added 20% across the VE tables and started dialing it in from that point.

that sure dont sound right. When you are FI, you are more than 100% efficient.
