The problemin this case is is to stop it ALL the time you need to pull 10 degrees of timing out of the whole boost map, the heat soak is that bad. On the dyno it pulls 210ish for about 10 pulls then it gets to the point its making 170 -odd witht the required timing pulled out. We had to take a median point so it was at least safe in the most condtitions (track with decent airflow etc), but unfortunately stop start driving just cant be compesated for without taking ALL the timing out. There is no AIT compensation in these ecu's either which isnt helping.
Water meth would be the best solution if a decent front mount is a definate no go.
