I think you are exactly correct. If you "flatten" the idle area somewhat, you may see the surge disappear.
Also, if you want to post the stock tune, so the compare feature can be used, it is easier to spot any radical changes that may lead to this. Sometimes a person will increase the entire pulse field a fixed % or number, and this seldom works well.
If you still don't fix it, send me the idle log with rpm, pulse, pressure (desired and act), main timing etc.
