I'm really looking forward to the results on this one.

I'm torn between the Dinan and ESS tunes. I like the flash loader thing from ESS, but the Dinan tune is supported by BMW. If they erase it they have to replace it. On the other hand, the Dinan tune is twice as expensive, so you have to wonder if it's worth the price.

I bet in the real world the results of both would be pretty close. Looking forward to some timed runs!
