3.6L V6 SIDI tuning nightmare, timing oscillation

[DVS JEZ]

Hey guys,

tuning my first V6 with HPT and having a few issue's that i would like to rectify. The vehicle is a Holden SV6 Ute 2011 SIDI

1) timing oscillated like crazy, ramping in and out from 6 to 21degree's during a WOT dyno run and also during light to medium load when below 4900rpm, as soon as it hits 4900 its runs as commanded. I have tried removing as much torque and spark reduction as i can (very limited in HPT for this model) but no change.

2) LTFT carry into WOT which i don't like.

Here is the current tune and a few logs.
These were taken using 2.25.2558beta software

what needs clarification is that are these cars running pure MAF or running pure SD

according to the airflow tab and high and low dynamic disable looks like its SD
