Visit the mopar section of the turboforums and read, read, read. Learn to sift thru teh crap. Learn who has good experience/advice and who doesn't.
As a somewhat-famous person on the mustangforums said - 'everybody blows up their 1st turbo motor'. Keep that in mind with your expensive R5P7. If you detonate a NA engine you ease off and drive home thinking about your next tunign change. Detonate a turbo engine and liekly the towtruck driver will ask you why you're crying.
