running boost 6 timing 4 I got a FATs time of 5.19 seconds.
output from vagcome is:
http://badger.ing.me.uk/vagcomlog.html
I was logging blocks 003, 020, 115...(I know cylinders 5+6 are missing from that as they are in 021, but damn Vagcom only lets you log 3 blocks

so looking at that I can probably turn the timing up a bit, as there is no pull back...and maybe when I get time I'll watch temperatures some more too and turn up the boost slightly

Car is: 2000 S4 saloon, revo, milltek full system with cats, green panel filter.
road was flat, dry, outside air temp was 14.5 degrees.
