Regarding loss of power on '90 200tqa.
I have a "Charlie spring" and  the fuel pump relay won't shut off uder
overboost.
No sudden cut off, I have experienced that.  I probably just let off  as
usual and then no more boost.

Doesn't  the spring hold the waste gate shut and the diaphram open it to
reduce boost?  Wouldn't this cause overboost every time you mash the
throttle?

I'll try to clear the codes and drive again.

TIA
Nick
