Finally dialed in idle and want to start tuning cruise & WOT, BUT AEMWB & AFratioEst aren't lined up. How do I get them to line up? WB sensor is located by the shifter area pretty far from turbo. Thanks

I can't view it at work but essentially you can start at low boost and do half a wot pull, make adjustments and do the last half of the rpm range. Make adjustments then up the boost a little etc etc.
 
"Half a WOT pull" Does you mean 50% throttle? or 100% throttle halfway up rpm range? Thanks

Knock sensor is leaking, and it's time for AFPR. I have no way of checking base fuel pressure. $300 right there. Do cheap AFPR work?
 
Half the rpm range. Look for used fuel lab or aeromotive regulators. People are always selling them.

I wasn't sure if you wanted to see a log now. If you do, it's attached.

Think I resolved the issue. I cut the fitting that slides into the fuel pump, removed the 2 plastic fittings and o ring, then replaced it with a rubber fuel line. Also removed the WB02 and it wasn't on tight. Cleaned the sensor, and reinstalled. AFRatioEst & Wb02 line up much better now. I just did a 3rd gear pull but I hit fuel cut just above 5k rpms. Thanks everyone!
