timing retarded??

[9240sx]

Iv had my timing set perfect at 15degs for a few weeks now,And last night i got into a race with a turbo supra so i turned on the boost controller which i have set at 10psi,And the car drove great with it,And today i went to check up on the timing and its now at 11 or 12 degs.Does the engine retard it self when you raise the boost or what?

Fix the timing and make sure the CAS doesn't move while tightening it. The base timing should never change as long as you follow the proper procedure to check it. The rpms should be 800 +- 50.
