having a discussion on another board about this...would just like to know the facts. Were talking about commanded vs. actual a/f ratios...my impression has always been if your ve & maf tables are correct your commanded pe should be pretty close to your actual a/f...and that the problem with gtp's or boosted fbodies is the map runs out at 140 so the computer is kinda guessing over 140kpa, am I correct in my thinking?
