I couldn't get a good O2 reading below 5500 (the O2 sensor is in the collector). I had to put an extension and a muffler to get the O2 to read in the lower rpm ranges. I found I was lean leaving the line (it never showed on the dyno). The car would stutter, pop and bang, leaving the line. With the motor cold. Richening it up between 4500 and 6000 cleaned it up.
