I have a 2010 cvo fxdfse2
I installed the T Max and v&h pro pipe.
I love it.
It's easy to install and self tuning is great.
It is much cooler now.
At stops the rear cylinder hasn't cut off yet.
1 year on now,no problems.
I would highly recommend it with a pipe change.

 

I've had mine on my SGS since the second month or so of having it; also ran one on my Lowrider. I've had one issue with mine, emailed them, they told me to update my firmware. Solved the issue in less than 24 hours. I've really enjoyed mine, and like has been said, once you get to understand the software it's awesome knowing you'll never pay another penny for tuning.

 

I've had several friends that have had a lot of issue's with the T-Max, personally it would be the last one I'd choose. Power Vision is the way to go or seems a lot of people like the V&H's Fp3 as well.
