Looks like you have to click on a button that involves signing up for the site, in order to download the file.... not many people will want to do that. I know I won't.

IDLE:

Everything looks fairly good except the spark advance and long term fuel corrections.
-idle spec 800, actual 800 = OK
-IAC = 26 = OK
-MAP solid at 30-32 kPa against a 102.2 barometer, indicating 20"HG vacuum = OK
-left side fuel trims are adding 7% fuel = marginal
-right side fuel trims are adding 11% fuel = outside normal limits, and should be closer to left side
-TPS = 0.67 V = OK
-coolant = 180*F = OK
-IAT = 84*F = OK
-battery = 13.1V = OK
-no codes = OK

Odd one is the spark advance ranging up to 29degrees at idle. Normal values are closer to 20deg for an M6 at idle.

Showing your mods as "Too Much" is real cute, but it really doesn't help anyone when they are trying to figure out what's going on with the engine. Why not provide a good mods list with the data, so people can try and match the data to the mods. Otherwise you are limiting the help you can get.

On the 4000 rpm log, the long terms are showing high, with the left side being larger than the right side in most cells, just the opposite of the idle data. Cell 2 shows it adding 17+% on both sides. You need to figure out why its running lean, and forcing the BLM's to add so much fuel. No knock retard or knock count increments, even though you seem to have a healthy amount of advance dialed in. Nothing unusual shows up.
