Suggestions to fix P0016 - Crankshaft Position - Camshaft Position Correlation

[samckitt]

Long story short.

Engine is 2008 TBSS LS2 (with LS3 heads, LS9 cam, LSA supercharger), harness is GMPP LS2 controller kit harness, ECM is 2009 CTS-V.

Immediately after writing new tune it runs perfect for a few seconds then starts spitting/sputtering, then dies.

code thrown P0016 - Crankshaft Position - Camshaft Position Correlation

Tried to do crank relearn, don't know if i completed it, didnt see anything saying it was successful.

Cam sensor is new, & is correct for CTS-V.

Suggestions/help...please.
