Thing you won't get while on a dyno while running there is the measurements basued on what I guess I'd call the 'consistent intercooler outlet temperatures' - therefore the air inlet density will de different on track.

Again I see 120-140, much higher than on an idealistic dyno run - I am certain the AFRs will be different due to this

Speaking of which, what are the numbers for air density decrease as temperatures rise?
aka, AFR change as a function of temperature change?
