Last I heard, Vivid doesn't do 335i's anymore....I'm not too sure about Dynocomp....If you look at their site, they say they can reprogram the ECU for the 335i...I emailed them about that a few months ago and didn't get a reply, I then called and spoke to someone about upgrading my ECU and they said they'd have to get back to me....That was mid-September and still nothing....
