Before posting a question in this forum, be sure you do the following checks:
No boost, vac, or exhaust leaks -check
Verify mechanical timing - check
Verify base timing - check
Ignition system - check
Motor health - check
Basic throttle body adjustments - check
Base fuel pressure and injector values - check
Compression ratio - check
Wiring and sensors - check
Properly calibrated and configured wideband sensor - check
Type of fuel - 93 octane
No DTC/CEL codes - check
ECMlink how-to videos - check, check, check, check x100

Here's some logs I took today after turning up my boost and tuning. First one is an idle log, second is a cruise log, and third is a short pull.
One thing I noticed while pulling was when I hit my max psi setting, my boost was really jumpy. What could cause this? It's shown in the log too.
Let me know what you guys think. Thanks!

I am not by any means a pro tuner but after taking a look, it looks like your Wideband is reading a little lean at WOT and at 91% throttle (still open loop so same as WOT). I would richen it up a bit if I were you and target 11:1 as a goal for WOT A/F Readings. That is currently how I have my car tuned, at WOT it dips to 11.3 and I felt that was close enough.

Please anyone else chime in if I need to be corrected in any way.

That is one thing I wanted to do for sure because I noticed that too. However, I'm not really sure how to do that just for WOT.
Also, any advice on the bov flutter? I've been reading up on it but have heard so much different stuff. I think I might try to use the quick release feature to see if that helps. I'm not sure whether to harden or soften if though. It only flutters with high boost.

It sounds like you may have to soften the BOV a turn to see if that reduces the flutter until its gone. What kind of BOV is it?

You can adjust fuel in the fuel tab under the rpm you want to correct. You have probably seen this thread before but im going to post it anyway just to make sure. Its probably one of the best i've seen in helping tune your car for cruise and WOT. It has a word document attached that you could just print and take with you if you dont want to keep switching windows on your laptop.

Thanks man that thread really you posted really helps. I actually haven't seen it before. I'm gonna try to use the quick release feature and soften it up. I'm still hoping it holds high psi though. It's just the ebay BOV that came with the intercooler kit I got. I know they suck but lack of money is keeping me from getting a quality one right now.

That document is somewhat outdated; with V3, you should leave the timing and fuel sliders at zero and use the direct access (DA) tables. You should first calibrate your fuel (global and deadtime values) and airflow (MAFComp) until your wideband reads 14.7 in closed loop, and whatever DA AFR table cell you are targeting in open loop. Once you can hit the open loop target reliably at any RPM/load, you can simply change the value in the DA table cells if you want a different AFR at any RPM/load.

Alright thanks! I've gotten used to using the DA tables for timing so I should be pretty comfortable using this.
