200TQA boost sensing question

[Robert Myers]

Good advice, Eric.  That said, however, I had the zener/resistor mod 
done on an '89 200tq when the car was about 3 years old.  This mod 
just involves fooling the ECU and not actually doing anything with 
the chip.  That wasn't what I thought I was buying but that's another 
story.  I ran that car for 60+K miles.  Then, 9 years ago, I sold the 
car (with about 120K on the clock) to another list member.  I just 
happened to hear from him just yesterday.  He told me that the car is 
still in use (including track time) in Colorado.

Given this experience I'm not too sure that the hazards are all that 
great.  However, YMMV.
