I've just bought a second hand profec b. Apparently when i was on dyno the solenoid seemed to be holding the boost well. after a week or so driving ard i wanted to expriment with the controller so i fiddled with it for abit.
Now. i seem to be getting 14.7psi of boost on 20% duty.
when i decrease the settings to 10 it's still the same.
is it a problem with my controller or is it just me?

 

It's just you.. Please re-read your manual carefully in regards to "BOOST", "SET", and "SET GAIN". PLease note the differences of the settings of each one..
