After a couple of times where I left the dsc on. I decided to start the car prior to my first run, rev slightly to get to operating temp, and not shut it off until my runs are over. This avoids the repeated long pushes of the dsc off button. Does this hurt me at all, am I letting some type of heat saturation hurt my power?

i doubt the intake will cool that much better between runs if no air is moving through it (i.e. stopped) than running.

efi cars can show dramatic increases in power with a cooled intake. but i think it will heat up more if you shut off the car.

however, much more likely to be an issue is the temperature of your tires. ive found the stock 040s really dont like heat- my first run is my fastest unless i cool them with a sprayer.
