Finally ready to supercharge

Well after a lot of research, filtering through the BS on other forums over what supercharger is the best I have decided Ill be ordering a JHM blower kit over the winter. Im about 2k shy of doing it now and want to do a few other maintenance things before we get to that point. I have a few questions from those that have this kit. 1 has anyone gone and had any additional fine tuning done on a dyno after install? Or is it perfect out of the box? Do you have to do a ton of logging and send them back to JHM several times to get a perfect tune? Most importantly question number 2, how satisfying is it to drive after knowing how your car performed prior to the blower? Is it truly night and day? This is my daily, I do a 30 min commute that is mixed rural, highway and a little bit of stop and go city. I want reliability at the end of the day, and thats why Im sold on JHM
