The 2006 owner's manual on page 2-31 says these are the shift vehicle speeds for best fuel economy, but you didn't buy your C6 for that, did you?
This chart shows when to shift to the next higher gear for the best fuel economy with a manual tranny.
Shift Speeds in mph (km/h)
Acceleration Shift Speed
................1 to 2...2 to 3...3 to 4...4 to 5..5 to 6
All Engines 15 (24) 25 (40) 40 (64) 45 (72) 50 (80)

This was posted a while back as a somewhat theoretical guide to shiftpoints. Another chart I saw listed 51 mph as the 1st gear maximum shift point for the MN6. Not that I'd necessarily recommend you try pushing these shiftpoints but I think once you exceed max rpm's in any gear, your computer will shut it down anyway.
M6 is 56 84 116 150 203 at 6,500
A6 is 50 85 131 174 236 at 6,500

I have a precise list of the shift points/speeds from gear to gear which i printed off of this site last winter.If you do a search (function above) you may find it,or i'll post the info after work tonight if nobody else does first.
http://www.eorsr.us/c6 click on the 'gear' icon for the combination you want, e.g. click the gear in the MN6 row, 3.42 column for the standard manual, or the MN6-Z51 row, 3.42 column for the Z51. The other columns are for different rear end ratios, for anyone who's thinking of swapping. I assumed noone would be swapping to a higher ratio!

It is a huge annoyance which is why most people are in higher RPMs when they shift into 2nd.
