problem... on a dyno the ambient air is cool and your runs are not back to back... on the track the ambient air isn't cool and you're on/off the throttle.. this means your IAT could go from 20 to 50 degrees and back down to 25 for example..
a big no no...
however if your tuner is switched on (which I hope so) he/she will tune the car not on it's limits so when it does get hot it the motor won't have a spaz attack and knock off its tits.. it will just run extremely rich.
Ideally, as IAT increase timing decreases as well as fuel.. and as IAT decreases, fuel increases and timing is brought back to what it has been dialled as on the dyno... if you want you could add more timing as the IAT gets even cooler
