...have had a lot of maintenace done, hadn't logged anything in a while, so I did some logging (VAG-COM), and i'm looking for thoughts on MAF g/s and Timing.

2001 S4 - H Box, Stock ECU, 71k miles
~60 F ambient, ~2k feet above sea level

MAF G/S (block 003)
Did a couple WOT 2nd and 3rd runs, max G/S value was 210.33
Average on the WOT 2-3 Run was 143.21

Timing d.BTDC (block 010)
Same runs, max d.BTDC was 40.5
Average on the WOT 2-3 run was 14.65

Boost (block 115)
Same runs, max 0.68 BAR actual
Average on the WOT 2-3 Run was 0.47 BAR actual

Though odd on the boost as my boost gauge (omori electrical with peak hold/warning) recorded a bit over .7 BAR (i set the warning at .7, and it went off, so something marginally over .7 bar on the boost gauge).

Thanks for any input.

to help you at that altitude.
