Bike runs great after dyno tune and no need to wait for the ecm to autotune.
Never shifted into 6th to around 60-65 before, now I shift into 6th at 50.

I went with the TTS Mastertune and a custom dyno tune. TTS was around $400 and the custom dyno tune was $300. They just use the TTS to program the ECM then take it off and you put it in your tool box.

I have the thundermax on my rocker. MAKE SURE that whoever you order it through specifies that it is for a rocker!!! There is a separate procedure for jumping out the connector for the ecm so their programming cable will work with the rocker. The reason is the diagnostic port on the thundermax is impossible to get to once it is mounted in the bike. The normal big twin kits don't come with the necessary adapter. I love the ease of programming this thing. My autotune module took a dump early this year and I just got around to sending it back for warranty. (I hope). The tech dept. is awesome! Very helpfull. They even helped my bypass the autotune so I could ride it in the meantime.

Yea, I had to do the same thing. Had mine installed at my local dealer who didn't install the cable. I'm not sure how they wrote the program to the ecm, must have been out of the bike is my guess? I didn't know about it until I had an issue. I knew before this to do my own work, but I had just bought the bike and figured since it was their idea that they knew what they were doing. This was in early '09 so it might not have been available at the time.
