| no signs of detonation, it was also a cool day @ 50 degrees in March, I have seen a few people on this board make better numbers with similar mods. My motor was also around 63K mileage. What is your point? Just because your car made poor numbers, you seem to only cry about the Denver guy's numbers? I have noticed in the 20 plus Z's I have watch dyno our A/F's seem to fall on the rich side? Is it the thin air? Who knows for sure? One of the local Supra guys had a chance to Dyno at sea level within a few months of dynoing at 5500 feet his number were almost identical on the SAE scale. I have bigger turbos now, and should have some good "PUMP" gas and race gas numbers soon.
