That seems low to me but what causes it, is a question.
Plenty of spark retard actors that could be punking the
tune, or could be the tune itself. Not much you can do
by speculating though.

WOT commanded in the main sprak table is higher than that stock. Intake air temperature can pull timing. Engine coolant temp can pull timing. Knock sensors can pull timing. And last but not least, the transmission torgue management can pull timing.

You need to get someone to log it with scanning software and pull the tune to see what is in each of the timing tables - with that information, it can be determined where the problem is...
