Check out the "engine modifications" forum under the X6 or the 3-series boards. Looks like there are cheaper alternatives that are still software-based and output more power and/or torque, but Dinan's the only one I could find with a warranty. There's a fair bit of debate over whether that's worth the significant price difference, but I'd rather have the warranty than not.
Have fun!
