Why have you fitted an MBC, your not gettin a spike at all and its only running 11psi? I cant see how running low boost could have that much effect on your timing. Maybe i'm wrong.
I think you can compare maps, both stage 3, both same spec etc... I think for stage 1 and 2 maps on different cars you cant as cars come with diffeerent turbos, cr's etc...
Personally i think your timing settings are incorrect, as if its running T9 plus lemmiwinks tweaks.
Talking of lemmiwinks, wonder what it would "read" from the ecu?
What are your long term fuel trims? Block 032?
