Here are a couple E85 Supras that we finally got to finish tuning last week. Both had some part failures that ended their initial dyno tunes prematurely. With how many random part failures, fuel system failures, FPR lines blowing off, bad MAFs, sensor failures, intercooler pipes blowing off, holes in intercoolers, clutch failures, etc that I see emerge in the short time that I have a car on the dyno it makes me wonder how some cars can last even a day on the street.
