Thank you all for your responses! After hearing them and discussing with Roman, I feel perfectly comfortable. I hafta give a huge shoutout to Roman @ ESS with his extremely prompt responses and eagerness to help his customers. Seems to be a great guy and he really makes you feel at ease with likely the biggest mod you could possible do.

I feel it may be a combination of the tranny not being fully warmed up at times and the ECU not being fully adapted yet. Prior the the SC, I would have a jerky downshift every once in awhile, but I think I'm paying extremely close attention to the way the car is behaving now that I have the SC on the car.

The kit has been performing great other than my concerns expressed earlier, so I will keep you all posted as I put PLENTY of more miles on it
