i am thinking it is due to the fact that AFRs needs tidying up but could calculating for air fuel ratios in the mid to high 11s send duty cycle all the way to 96%?

vehicle had in N1 cams

Sounds about right, but do check the fuel pressure.

E60 K=308

Yes, mine has N1 cams at 0/0 and my base was the E60 bin attached, but the current one I'm using is highly hacked by now.

I didn't just switch the VQ tables. I have done alot of work to the entire bin, adjusting the k-value included. However, I had my k-value to low. I did another run with o2 disabled and made the proper adjustments. I took said value from 272 and ended up at 305, which seems to be the sweet spot for my set-up. Thanks for the suggestion of 308, it was pretty much point on!

The fuel map I made (I pretty much adjusted every cell, some extensively) seems to be pretty good now. I no longer get the lean AFR's!!

Car finally starting to respond!!
