re: 200tq boost...FIXED! (I think)

[Eric Harman <ericha@wrq.com>]

Ah-hah!  I've noticed that same problem, too, lately.  Recently I've found some
really good ramps (just the right incline, I guess) to get the boost up to 1.7/1.8
quickly.  Lately I've noticed a realy sudden cut-out of power when I hit the
max boost level.  I go in for my 60K service this Tuesday.  I'll have to see
if the problem goes away.  I don't know if it's a new problem or not because
I only just found how to get the boost to climb that quickly.  We're planning
on doing the pricely Bosch Platinum route, so I can't help you on the other
plug question.
