Your question has been repeatedly answered very well, but I would like to add one thought - if you just spent that much at FAME, why not talk to them about the problem?. Did they work on the pump? Brad Bean at FAME is a great guy and a supporter of PNDC. In fact there will be a PNDC Tech Session there on April 28. You might even see a supercharged DeLorean there..... -- Darryl Tinnerstet Specialty Automotive McCleary, WA
