Yes, the stock car will get better fuel economy under boosted conditions than a tuned car. After all, it is making less power and using up less gas by running much leaner. But I suspect most customers are going to be able to live with a couple less mpgs under boosted conditions when the upside is 75lb-ft more torque. Unfortunately, this was a tradeoff that BMW wasn't allowed to make for a number of reasons (fuel consumption targets, M3 canibalizing, emissions standards, etc,.) Fortunately, folks like us operate on a different set of constraints.

PS. Good God Dustin! Look at the time. Don't you have work tomorrow?  |
So if I put your software in a 335i and drive like a normal person, would I have worse fuel economy then the stock model?
