John,
because of space considerations on the low mounted turbo,..I've
removed the wastegate assy and substituted a spring to hold the bypass
flapper closed,..I just experimented with spring tension to get the boost
right. Its in keeping with my KISS
philosophy,.....I'll probably have to install a real wastegate in the
exhaust pipe eventually.
