A few seconds update time is a hell of a lot better than 90 seconds when you're the one paying for the dyno time. I'm chasing the realtime thing because the C5 PCMs and later can do it with that stupid subscription-based crap HPTuners, but I'll take a 90% decrease in update time too. Sucks having to shut the car off and restart it but hey. At least you're not sitting there for a minute plus while the thing flashes the changes.
