I just looked on Ronnies HD at the part numbers. The ECM part numbers for both years are the same, but they have different notations and both state that they need to be flashed when installed.

For 2007:
604801



For 2013:
604802



I am guessing that you need to have your ECM flashed to match the new motor.

I really wonder if one of those Cobra auto tuners would do the job. Don't they override the ECM, or do they work in conjunction?

I will be curious to see what you come up with. Isn't that the 1250 motor? If so, you should get a descent power up.
