Stiffer Wastegate Spring

[Lawrence C Leung]

Dennis,

Go for it! Let me know the easy way how? (sound's like a sales
endorsement, doesn't it?) I take it you haven't had to jumper the fuel
pump or disable the rev limiter or other safeguards in order to do this,
am I correct? Also, how did you (and do you need to) enrich the mixture?
Shouldn't the WOT switch do that? Finally, BTW, what kind of boost are
you getting (at least on the dash gauge)?
