You will find technical points on their drawbacks, lots of sales blather saying they are great, then lots of owners that like them and a few owners that have had problems and some disasters.

He didn't answer, hence my second question. I know all about the PB's and tunes. I had/have tunes on both my former M5 and Z06 9 (among many previous cars). Additionally, I've worked with tuners as a beta tester.

The PB's seem to work well on the diesels. To globally say they "suck" and not explain why, doesn't add anything to the discussion.
