Also if you hear that "pinging" sound under load. Not good.

Just pull a plug! Its going to be the best indicator your going to get. Unless there is an exhaust leak or o2 sensor failure your car should be running fine.

your car is likely not running lean. the PCM is set up in a way that makes it almost impossible for you car to go lean unless you add some serious internal mods and heads without programing your computer. or the more common way... add nitrous without adding fuel
that can get ugly!
