I have the 2010 990 Adv, made my own 2-1 exhaust. Tried the stock map, it was ok, but not great, somewhat unbalanced with surges and flat spots.

The Akro map is way too rich, even for the Akro exhaust and the mileage sucks without the O2 sensors.

Get the TuneECU program and cable or find someone. Use the: power-trippktm990advwings.hex program, which is for the 09-up 990 adv with a 2-1 exhaust. It is the closest program you'll find. Good mileage at 42-45mpg. Throttle response is incredible. He did very good work with the ignition mapping.
