Dyno numbers are in.. Technical help needed!!

[Kerpal]

What i dont get is, how come i didnt hear a ping on the dyno, yet on the way home, it was clear as day???

Lots of variables... maybe you're under more load on the street, maybe hotter air temp, heat soak, etc. Gotta keep in mind that a dyno can't perfectly replicate all the different conditions you'll enounter driving on the street. If you're hearing pinging you've got a good reason to be concerned, be easy on it until you get it sorted out...
