Re: Adjustable Wastegate

$50 for just a spring? I paid less than that for a whole used WG! I too
added a stiffer spring to the 91 200q and do see *much* faster spool up -
with a stock chip all I get is 1.8 bar. By using the adjustment to add more
preload to the spring, I can actually hit the overboost cut out.
