With the A9L and a base timing of 10-degrees, you'll have a total timing of 27-degrees by about 3000rpm. This should be safe if you are rich as described at 6 psi. Every car is different though so my real recommendation would be to pull a few extra degrees until you can get it on a dyno. Hopefully the shop you go to can actually datalog during the run using something like a SnEEC datalogger. That will let you see what kind of timing you're actually getting under load.
