Another request for reading data log

As far as I can tell my data log looks good but there was one piece that I was concerned about. I did 2 4th gear pulls from 2500-7000 like Cobb says to do and they looked fine. When I did a 2nd-5th run I had some knock feedback in 4th gear.

3rd Gear pull:

4th Gear pull:

2nd through 5th pull:

Thanks in advance.

Additional Info:
2005 STi with 52500 miles bone stock. Just flashed to Stage 1 for the first time in it's life.

Someone recommended I let the car learn the tune for a couple days and another person said the feedback might have been a sloppy shift or a bump in the road.

That's just a bit of shift knock... nothing to worry about.

One thing to note is that your DAM is still at .5 The ECU will likely try to advance it to 1.0 at some point which may cause some knock in parts of the RPM range. I would recommend driving the car around and logging again in a week or so.

Can you tell if you are boost creeping by watching Wastegate duty?

I see I'm hitting over target boost of 17.5 a little. Also how do you go over 100% on inj. duty?

This an OST Cobb stage 2 with catless TBE.

You're not creeping because boost continues to drop at higher RPM's. What you're seeing is a slight boost spike and waver. This is fairly normal with an OTS map. It doesn't look like you have any major knock events in that log, so that's good. The 100%+ IDC means that your injectors are maxed out. Generally they stop flowing any more past about 97%. Without seeing wideband a/f data its impossible to tell if you're running too rich or possibly too lean from not having enough injector and fuel pump flow capacity.

Thanks

Thank you very much Ed!

Hope you got my PM. Sounds like My new question is in line since the injectors are maxing out.
