5.7L Ignition Timing Table - Feedback

The following table is a lightly adjusted timing table from EFIsource, mostly just around the idle cells and it seems to work well in that area.

My 'Cuda has 100 or so miles on it and I am feeling more interested in tweaking the tune for power, since the drivability is sorted out pretty well.

Please provide feedback on the table below based on your experience, from what I read, the mid-range is probably a bit high..

The X axis is obviously RPM, Y is MAP [kPa]. 100kPa = WOT, ~45kPa = Idle
