It almost seems to be associated with the knobs on the head unit 
being jostled, but I can't be sure.

I'm looking to chip the car, but I want to make sure all is okay and 
up to par.  Aren't I supposed to compared the "static" pressure 
value against the "on boost" pressure value?  Like, subtract the 0.9 
bar "ignition on, engine off" value from the peak boost value of 1.3 
bar?  That's a 0.4 bar delta.  Is the 1.42 bar max boost on a stock 
system, refering to an altitude that is 1.0 bar with the ignition on 
and the engine off?

Thanks,

Ken
