Another oddity; this car was set up on flex but was exclusively run on E85 when it was in California. We don't have as much E around here so my brother mostly runs it on pump gas; we noticed the car was running extraordinarily rich, so we had my tuner data log it when we threw it on his dyno. Turns out it was running at a lambda 0.74 average through the rev range, so we immediately retuned it; we did not datalog the old E85 tune. I'm guessing this had something to do with the elevation change from CA to UT, but I also figured MAF would do a better job at correcting that. Regardless, the car went from 610 WHP to 710 WHP on pump gas from this retune lol.
Elevation also plays a big factor as the dyno is using a larger correction factor when using SAE or STD which shows you are making more power then actual as elevation climbs and less as you go down. So cars always tend to show the ability to run more E85 @ high elevation because you are making less power uncorrected vs a car @ sea level.
