Leib has a valve controller that works, also takes care of opf delete errors, and a few other option,I had it on my car for a few years.
The new tuner had some trouble with it when i switched to bootmod3 and he ended up pulling it out.
but the tune has it programmed always open ,so it's not a big loss :-)
