Hi,
I'm wondering if someone has any recommendations for a tuning box for the B48B20B engine in a 330e? I would prefer to just update the cars firmware but it's a company car. I spoke to the founder of the company and his exact words were "I don't care as long as you pay for it and it is possible to remove if your engine breaks down on the highway or before a service or warranty issue". So that's why I'm more interested in a removable box than changing the software in the car itself.
So, any suggestions, recommendations or warnings from anyone?
