137 is the down stream o2 sensor that i dont have lol and 401 is an egr insufficient flow. they didnt effect performance since i ran my fastest time with them set.

P0401: Insufficient EGR Flow
P0137: O2 Sensor Voltage Low, typically either catalytic converter related or either primary or secondary oxygen sensor.
Sure would affect performance if your kitty's getting clogged and it's not just a faulty sensor. And the EGR one, my mom's 3400 had that coming on intermittently when the headgasket blew, heh.

J, upload your .bin file somewhere so I can see your settings and compare them to your scans.

Well, you are faster, but not by much. 0.016 to be exact. Would this make us equal?
Jon, what was your fastest time ever?

Jon, your spark might be commanded a little high.
I can tell you that in the Spark tables, I dont' have ANY cells commanding more than 15 degrees when I'm at or above 90 kPa. Try cutting your spark down for beginnings.
Just a little at a time, then compare to see if it makes a bit of difference for you.
Also point of note, I noticed your IPW's spike periodically, as if there is not a smooth transition between MAF cells. You probably want to work that out as well.

i dont have a downstream o2 sensor and i guess i forgot to turn that code off and i have no signs of a blown headgasket.

thats the difference between boosted vs non-boosted. i am supposed to be able to run higher timing...or so i thought.

the one i used at the track:

changes i made when i got home ( i added 3% to all MAF cells 4000hz and higher):

You would think so. But looking at your scans, that's the most likely culprit right now.
Keep in mind, there are other things that can cause KR, like lack of traction (wheel hop), bad motor mounts, loose exhaust connections (especially at the headers) etc.
Headers that had slowly worked their way loose (before initial retorque) caused me to go on a mad witch-hunt for KR through tuning, and had no effect. Once I torqued down the headers, it went away. Pissed me off.
