Re: wastegate spring related stuff


I was under the impression that the IA box uses a resistor network to scale
down the output from the pressure transducer in the ECU.  If this is true,
it would raise the overboost limit as well as change the timing under boost
conditions.  It may be possible to get away with this approach, but it
certainly doesn't seem optimal.
