I am sure all of us are getting sick of seeing "Look at my Log" threads everyday and are praying this doesn't turn into E90poop. So, I figured it would be worthwhile to start a thread where we can try to keep all of the logs in one place. Hopefully this also makes it easier for all of the experts to provide feedback since it is one thread instead of many.
See below tips to try to take advantage of the help as best as possible.
Be sure to include all pretinant vehicle info. Model year, mods, fuel, etc.
datazap.me seems to be the go-to for logs on this forum. Credit to @jpsimon for creating a great platform.

1) Setup the datalogging list or just use the Default list.
*RPM, Accel Pedal Pos, TPS ACT, Load Requested, Actual Load, Req Boost, Boost Mean Abs, Cyl 1-6 Timing Correction, Cyl 1 timing, Bank 1 and 2 lambda(AFR) and Boost
2) Find a long, straight, level and empty stretch of road.
3) COMPLETELY DISABLE traction control, if you do not do this you will have throttle closures
4) This step depends on how comfortable you are/how safe it will be to redline 4th gear. If you are comfortable doing that, then you should a 3rd-4th gear pull. If you are not comfortable at those speed(~130mph) then do a 2nd-3rd gear pull.
4.1) On the AP go to the logging menu and select datalog. The screen then should say something like "Press OK to Begin Recording"
4.2) Get your RPMs to about 2,500. Allow your RPMs to settle and then press "OK" on the AP IMMEDIATELY before going WOT.
4.3) Be sure to hold the Accelerator to the floor all the way, do not allow it to return at all.
4.4) Shift into the next gear and go all the way to redline and then let off the throttle.
5) Once you have your datalog recorded you need to connect it to your computer and use the AP manager to transfer it onto your computer.
