If you read the hundreds of posts from all different forums theres ppl asking how to stop their engine from overfueling as it can make the engine run lumpy, and your asking to do it on purpose. Your mad.
If you really want it popping why not try a fuel pressure regulator and turn it on full, that should see some flames.
But in my opinion id just be happy the engine runs decent and keep it that way, when you start ptching things go wrong mate.
Trust me you learn from mistakes.
