I feel like a lot of the techs don’t know if there is necesarily an updated flash for a car. I also wouldn’t take my car to collussey. I doubt they deal with many SS/SC’s. I have only every seen one on their lot and that was the yellow one they recently had. I had them do some warranty work on my turn signal one time and the tech said he never knew they made a supercharged model. If you are from around that area, I would suggest Sun. They did my stage flash there and told me they have done quite a few stage kit installs there.
