Hi, I'm new here. I don't like the 18mpg I'm getting from my E34, would a chip help? Most of them talk about hp and torque but I've also heard that it affects gas mileage, although some say it goes up, some down.

I'm thinking that one of these from eBay is probably a copy of a more well known brand like Dinan, since a chip this cheap probably has no R&D of its own.

Any ideas?
