To start off, I've got a 2015 street bob, stock heads/internals/cams, etc. with a ness air filter, v&h short shots and a pcv with no autotune. The bike's run ok for about a year, but now i want to get more out of it and i feel like im really limited trying to adjust fuel and timing without really knowing how its affecting the bike. Essentially, I'd like to get some data logging sessions with O2 sensors to really nail down afr, but from what I've read on some posts already, some people really seem to prefer the SERT over the power commander. I guess what I'm asking is, for people involved in the tuning of their own bikes, is it worth it to ditch the PCV and get the SERT, or to go in on autotune for the PCV

 

No comparison between the two. The PCV can be modified with your laptop and you can adjust every field imaginable including timing. This is the second bike I've installed it on and swear by them.
