This is why my and every other "dyno" tuned only car I have seen locally never produces the same boost # on a 1-2-3-4-5 gear pull as it did with a straight 5th gear pull on the dyno. Rally cars are all "street tuned"
Yeah...I'm aware how you capture it. On a dyno though you usually just toss a wideband o2 sensor into the tailpipe. I was curious how it might be done on a street tune. If the stock o2 sensor readings were used I wouldn't think they'd be as accurate. I'm just using my experiences coming from the Honda community. The street tunes I've seen weren't exactly wonderful.
