Didnt realize till later in the day when i replayed the logs...

Also im not sure what software is being used... or much about tuning e46's at all for that matter. But it would be nice to get a fuel saving tune... it made a big difference on my other car.
Yeah, I mentioned overlap. But 14 or so at WOT under boost is crazy by anyone's standard. I see your sig, you're playing with the Quarter Horse, right??? Nice little tuning device. Has it's limits like a TwEEcer, but it's nice. Let's not high jack this dude's thread, he built a hell of a car. I would hate to see him melt it down by taking some dumb advice about tuning at WOT and boost for a 14:1 AFR.
