I've got the ThunderMax on my 2010 FLHXSE. Had no problems with starting as you describe. Might ask your TM dealer to download an update from the net directly to your bike's TM. TM comes out with a new software update 1-2 times a year, it seems. Bought my ThunderMax a year ago and TM has come out with two updates since I bought it.

My TM made a huge difference in torque and hp. Also, I put Rinehart True Duals on it at the same time, and that opened up the back end.

UPDATE ON THUNDERMAX AUTOTUNER:
My 2010 FLHXSE started getting hard to start, dying at idle. I decided to check and see if Zippers had a new firmware update available. they did from October 2011. So I downloaded the update into my ThunderMax ECM over the weekend. That fixed it -- no problem starting now, and idles fine at 992 RPM as set.

Then I remembered what happened. I decided to work on some wiring under the fairing and, as instructed, i pulled the main fuse. Forgot that pulling the main fuse (as Zippers says in their ThunderMax manual) will cause the TM ECU to lose its settings. So I should have re-initialized the ECU after plugging the main fuse back in. Just turning it on for 20 secs, then off for 15 secs, then start it and let it idle for 15 secs. Not a big deal. But my ECU was trying to run the bike without all the settings it had before I pulled the main fuse.

Now the bike is SUPER responsive to the throttle! And my mpg went from 35 to 41 mpg. FYI.
