the file i have linked above is a stock map for a ls1 engined hsv clubsport from 2004. if you look at the upper ranges of the ve table, high load high rpm area's the values are 103-105. now my understanding of how efilive works and the tuning of these vehicles means that you are basically seeing positive pressure ( or in other words boost ) on an na engine. it doesn't make sense to me thats all.
