I just received my EMS and I have a tune scheduled for next Friday. The shop (Dyno-Comp in Scottsdale, AZ) said if I install the ECU, all I pay for is dyno time and they'll do the tune for free. My question is: other than loading the base map and of course removing the old ECU/ installing the new one, is there anything else I will have to do so my EP will still be drivable?

My options are:
1. Let the shop install the ECU (an extra ~$100)
2. Install it at home (I'll need the car drivable)
3. Load the base map, get to the shop early and install it there in the parking lot


I have no tuning knowledge, so any advice will help out a whole lot.
