Hello HT, it's been a while. I'm having trouble getting BBG working properly and would appreciate any kind of help. I am running a hand fabricated (by me) bottom mount divided manifold with 2x Tial MVS wastegates, Holset HX35 turbo. The problem is that duty cycle does not change boost pressure, it always fluctuates between 15-20 psi and surges like mad.
Output test for solenoid verified it is working. tried changing frequencies, currently have it on 33hz. Same problem end of last season, this is a new boost solenoid.

The log wouldn't attach so here is the googledocs link you can download it
