Alright folks. I decided to do some graphing yesterday using my VAG tool, and maybe some of you folks can help me out if you think anything seems wrong.

First up is the Boost readings. This is still in 'mbar' values. Sorry if I did not get to change to PSI or anything. Highest value according to the log is 1710mbar. The values are all in 2nd gear from 2600 to 6400 on the tachometer.

The second one up is the MAF readings. This is in 'g/sec' values. Highest value recorded according to the log is 185.8g/sec in 2nd gear from 2600 to 6000 in the tachometer.

The third and last one up is the Torque readings. This is in 'Nm' values. Sorry, but I did not get a chance to convert it into 'lb/ft'. Highest value recorded according to the log is 490Nm in 2nd gear from 2600 to 6000 in the tachometer.

I might need to do a few more runs, but it would be great to have somone to help. I'll wait until my nephew gets back into town. Kind of hard to do runs, log the data, and click the button to stop it all at once. What do you guys think? Is 490Nm kind of a smaller then expected value? Do I need to do 1st gear or 3rd gear runs instead?

Not sure I'm of much help but... First, I guess this is the RS6 you measured.

Secondly, the misano red RS6 Avant we chipped at ACE Competition / Hohenester did a confirmed 560 Nm of torque.

Not sure in which gear though as I was too busy with other things. I guess there's a limiter in some of the gears.

Try other gears and see what you get. You should reach a max of 560 Nm, if the technique is the same as the one used in the blue VAG diagnosis box.

Here (http://www.onlineconversion.com/power.htm) are some useful conversions of power. Hope it's of use.

Thanks for sharing the charts and information you've gathered, with us. :)

Even if you measured a 490Nm torque those are quite impressive charts!
Thanks for sharing!:)

The measurements were done on the RS6. I will have to try across all gears to see if changes are different. I will continue to share all my logging with this crew.

Maybe next time I'll make sure to include in Nm and lb/ft, or mbar and PSI.
Thanks for the conversion tools.
