You can add too much timing and lose power without any irregular combustion, i.e. detonation, pre-Ignition and detonation of fuel before ignition. The top is the stock timing table with the altered table below it. Most of the table look like it should, but the lower right gets super conservative. I have been playing with it for a while and feel it is pretty close. I have a new tune ready to load with lower threshold for PTE, part throttle enrichment.
If you try to compare it to HPT the table is rotate 180 degrees from the syked table. I have only seen one HPT tune and the numbers seem to be the same, but the X and Y on the tables are different.
