Welcome to the forum. 
Valvetrain ping? Do you mean when you floor it the engine is pinging/knocking? It is a very unpleasant sound with hesitating. When does it happen? Does it happen all the time or just when you go WOT (Wide Open Throttle, flooring it)? Could you give more detail?
I think that's strange because the hypertech programming doesn't change the timing by very much at all. Make sure you take your foot off the gas whenever it pings, because it's not good for the engine.

This one is stumping me. Yes it's a possibility, you will get pinging/knocking if you are either too lean or you're running too much timing. Obviously the hypertech is changing something that the engine doesn't like. I just can't figure out why... yet.
