On build 7.5.6 (133) I've logged instances of both LMM's and LBZ's failing to engage the turbine brake which I've written into the tune using the desired boost table (amongst others). The scripts have worked in the past, but recently stopped. Further investigation points to no significant change in 'desired boost' PID when I switch the DSP. It should jump up 200kpa like it has in the past.

If you need any more information, let me know and I'll be happy to provide it. Tunes and logs can be sent via email if necessary.

Hopefully its something simple, thanks guys
