I have been using the TMAT on my 2007 Ultra 103 since January 07 when I installed it.. Install was straight forward and easy. Read the instruction manual twice, 2 times, and then do the install. The bike is cooler, runs better, and I have changed mufflers several times. Currently running Screaming Eagle Touring Performance 4" with Fullsac 2' baffles I put in them...
Customer service can be an issue there but I did get a custom map from them for my 103" engine. Bike runs like a scalded cat, has 21,000 miles on it in 2 summers and hope to put another 11,000 on this summer. Never had a problem with the TMAT and I just "set it and forget it"..... OH... 39-41mpg depending on how hard I push.... Bike does not wake up until I hit 3000 rpm....
