I had called and told them that I get the check engine light every time I reach a certain amount of speed in my 335i bmw and they told me all I need is to get my car tuned. So I go and get my car tuned from them. They ended up not being able to tune the car because that check engine light came on like if they didn t know about it. So they weren t able to tune my car but they still charged me. They also told me they ll call me back the following week and they never did. This was a months ago.
