PCIII vs. PCV vs. SERT...suggestions?

[Ridingmtnroads]

I bought an '08 night rod in Aug & it's run lean from the get-go.  I've looked into what to do about it and found a number of options...PCIII, PCV or the SERT.  I've heard the PCV is self adjusting, and gives a greater range of settings, but wonder - what bugs still need to be worked out.  Anyone out there have experience with any of these? 
My other question is: will any of these controllers do the job without messing with the pipes/airbox?

Thanks!

The PCV is not self adjusting by itself you need to add the autotune module to in order for it to be self tunning. I have read nothing but good things on the PCV w/autotune and seems to be having less problems than the thundermax
