Any suggestions of opinions of it being a little too aggressive or conservative.

Thanks in advance

You can't evaluate timing without checking engine load / AFR - are you holding 14 psi consistently? Generally speaking, timing should be advanced as engine speed increases, unless there are other considerations such as trying to keep torque artificially low. You would typically expect to see less timing at low rpm on a turbo setup to keep torque low and more timing at high rpm as torque begins to drop off. Likewise if engine load is lower before the turbo is making maximum boost, adding timing can help increase torque to make up for the lack of boost.
