[s-cars] Re: Wastegate Spring

[William Noland]

When installing aftermarket chips, the wastegate spring is normally 
cranked down about 6 turns, which prevents the wastegate from dumping 
boost prematurely. No reason to replace the spring, that I know. Maybe, 
for the extra $50, they just tell you to crank down the spring.  :-)

TAP's upgrades haven't the most popular on the list. The hp figures are 
a little optimistic. MTM or IA chips and 3 bar sensor are the ticket.
