Nye, my eyes thank you for updating the site:

Funny how Nye's and Mark P's FATS calculators show different times.
I guess the car is in a pretty happy place. ;-)
P.S.-Here is the link to previous post filled with Mark P and Nye graphs: <a href="https://forums.audiworld.com/s4/msgs/2451800.phtml"> Click me!</a>.
Same Lemmi Tweaks as before except for start-up and warm-up are both set to 110% now (no effect on WOT). Also, same weight except for any difference in amount of gas.
Difference in MAF readings can be attributed to boost being 1 # lower across the board...although I believe some of the difference is offset by lower temp and higher pressure (both causing denser air)

Nice data. What's interesting is that it takes you ~3.6 seconds to get from...
4200-6200 rpm (FATS) but it takes you less time (~3.25 seconds) to get from 4000-6200 rpm (I just looked at a portion of your FATS+ time). You'd think that the extra 200 rpm would require more time. Am I missing something or is there some kind of momentum built up.

Some good figures, but I would be concerned about that much timing pull?
Looks like you've advanced your timing a tad too much and maybe need to take it back a notch - I was under the impression that 5-7 deg retard was as high as you should risk.
