Default Procharger timing issues

Hey everyone.This is my first post here.I have gotten alot of good info by searching but I have one issue yet to resolve. I have an 03 Z06 with a Procharger D-1SC and 42# injectors I am trying to tune with LS1Edit and EFILive.Overall things are going well but I have noticed that the timing advance (ADV) drops as rpms increase even though there is no KR displayed.ADV is below 10 degrees by 6krpm.The timing table in that range is set to 15 and I have the IAT table zeroed out so there is obviously something else influencing timing.It seems to me I am sacrificing a significant amount of power by not keeping the timing up higher.Any help is greatly appreciated.Let me know if you need more info.TIA

Try disabling the COT.

Already done.I set COT Enabled = False.Any other suggestions?Is it possible that the pcm is compensating for the additional airflow and keeping the timing low? It seems like there is another table somewhere the pcm is looking at since I'm not seeing any KR.

If you send me your Edit file I'll look at it for you and see if I see a problem
Slowhawk@attbi.com

Could be just the timing map.
