today 8.8.18 I drove by Bavarian Workshop and asked Marc if he could check and see if my Dinan shockwave was still installed. The reason why is that when I went to Thousand Oaks BMW they had to reinstall software on my car and I told them to make sure to reinstall the Dinan Shockwave. They told me they did but couldn't verify!!! Anyway went to Marc and he checked it right away, and of course it wasn't installed I waited about a half hour and I was on my way with the shockware installed. Thanks again Marc ! you guys rock!
