Good call on PPK possibly being the special tune that the OP is referring to. It is available for all model years of the 135i though, not just the 2011 model year as the OP thought.
I think PPK is known more for the exhaust pops and crackles during engine overrun than the small increase in power. That sound is addicting and makes you want to turn the stereo off and roll down your windows so you can hear it better.
Also, PPK helps to eliminate the idle fluctuation, throttle lag, and lurching forward issues that have bothered many (but not all) DCT owners. It hasn't cured these issues for all of those that have them, but it has worked for some.
PS - agree about the Dinan flash. I love mine and would definitely get it again.
