Sillber turbo dobec and rpm

Hi , after a year from the doo i forgot how the dobec works , ive read the sillber manual but could someone explain better ? For example is the green general value an increase there will increase all ?

What is best rpm for 800 etec -16? Got 8000rpm now with 3psi with barely no snow, going to set it to 5psi when there is more snow.

Optimal afr? 11.8-12.3 WOT ?

Ive got a strange noise this season it sounds like there is dropping water on an hot plate it sounds almost like a sauna when its heating up . Anyone exp that ?

Anyone???

Got 8100rpm now at click 1 and 7psi , at click 3 ive got 8400rpm ( little snow and just powder).

I see good afr at WOT around 11.8 . But i feels likes it pushes in more fuel when letting of throttle it does not drop rpm as fast as it has been .
