I've got a TMAT on my '07 SE Ultra & I love it!
The tuning options are great and if you've got access to a dyno machine, it can be dialed it even better.
(I got to use the dyno at New Orleans HD dealer & got 13hp/16tq more after several months of learning ALL the settings)
Some dealers don't like the Thundermax & may not want to warranty motor issues if you use it.
Were the changes needed in timing or fuel?
