haven't checked what it says while driving but at idle the other night it matched 8% command and 8% actual position.

Seriously, 8% at idle is going to make vacuum at the intake and is hard on the face seals of the turbo. -- It is also an indication that your tuning is severely out of date
(several years old by now) and there is no telling what else needs upgrading. Setting a turbo that low at idle has not been done for a few years now, as we have all learned that it is not so good for them. There is also a lot of bug fixes in the programming that have been addressed for 871's since then too.

I think you should get with whoever tuned that thing (I think is was Uni, back about 2015 or 2016) and have the program updated. Your welcome to pull a copy of the program out of the ecm (using CT) and e-mail it my way if you can't get a hold of him or Mommaburt. I can update it if need be if ya e-mail me the file out of it.
