My question is what do I do since I'm bogging my car down from too much fuel (rich) while the o2 is saying that it's running too lean. and as soon as it gets past 5lbs of boost the knock sensor goes crazy and shoots all the way up, no matter what the hi throttle settings are(richer or leaner) Edit: I have a pocket logger with the MMCd, but how can I upload it to my computer?
