Hymey... everything you say in this thread is correct... My arguing point is. if you get max cylinder pressure you get max torque and the only true way to find this out is in a dyno...
Using efilive, i haven't had a car have a different A/F on the dyno than on the street and I test them ALWAYS.. they are pretty much DEAD ON.
On Fords, they usually get a tad richer on the street.
My point about advancing timing @idle was to show you that you could advance timing way beyond your max torque output and NOT get any knock.
One thing would be: could you post your HP curves for your best ET vs your best dyno graph?
Maybe the climate on the dyno changes a lot. It has always been my purpose to put the car as far close to street conditions in the dyno to get an accurate tune. Hence why I don't get much issues with it.
