Has anybody that has done upgrades on their new scooter tried a Thundermax EFI tuner with the auto tune feature ?

 

Hope this helps

I have had the ThunderMax ECM w/AutoTune installed for about 1100mi now. I did the installation myself.
The bike doesn't have any radical mods, just Stage I stuff - AC and exhaust.

I am 110% satisfied with it. It corrected EVERY rideability problem that I had with my 2006 Street Bob.
No more surging, stalling, stumbling, or throttle hesitation. No more popping on deceleration.
There is a very noticeable increase in low end torque. I no longer have to downshift to pass while in 6th gear.

I cannot praise this product enough. It just WORKS as advertised.
H-D should be installing these at the factory, but won't.
The dealers would scream about the loss of SERT and dyno tuning sales.

More info here from an earlier post.

If I can answer any specific questions, just ask.
