Care to share the tools to use?

 

I do it a number of ways.
The "trick" way is a simple, cheap ADC with an input from the pressure sensor from my boost controller, which I hook up through a virtual port to the WBO2S input on the AccessTUNER software.
What I do when I don't want to lug around the laptop or run the CarPC for this is just hit the logging function of the E-01 and move the data over to the spreadsheet from the AP log.
As long as you know where you were in the log, the RPM or time stamp will get you lined up.

 

Added torque charts to the dyno thread :
