It's normal most all supercharged motors have a surge at low rpm.as for being rich mine is a little not to bad the last thing you want is it to get lean on top.then it goes boom. What number did you get?

Centrifugal superchargers all do this. My Terlingua bounces around a variation of 400rpm with the Paxton on it.
