Default tuning help

my car runs a little rich, sometimes it backfires , and sometimes i get a lean pop , all out of the exhaust, car has no cats and a basic tune for code deletion, car is not daily driven either, its annoying and i need a fix until i get my heads and cam in for a dyno tune, any help is appreciated. thanks chris m.
