This would give you a baseline to start from. Only way to optimize is like said above post on a dyno. This takes lots of money in tuning time....which is why alot of guys in the know dont offer up details.
This might be an opportunity to try the Dynolicious app for the IPod Touch. Change the timing and make acceleration runs to determine which value yields maximum torque.
