I am working on honing in a new set of injectors on my 1.8t awm ch box a4 and I can't seem to get idle stable, but after looking into my issues, I feel its a vacuum leak.  Could anyone take a look at these logs, specifically requested pressure vs actual pressure.

req/actual pressure are only relevant for WG control.

vac leaks are more easily seen in fuel trims.

Ok.  Ill recheck fuel trims.  I have krkte nailed down and ill use fkkvs to fine tune inconsistencies.

On a side note, I'm hoping to add more load and the maps max out at 140.  The 225 BAM has longer maps, but runs a lower compression ratio and ive noticed when maps are aligned the BAM has more spark advance.  Would you interpolate the ch maps for higher loads, or would you interpolate the 2.7t mbox maps with equal compression and displacement per cylinder, or adjust the axes for the BAM to accept the 2.7t maps?
