I am new at reading these graphs but it appears that something shits the bed at about 5 seconds (5,300RPM). Before that the boost is basically tracing the boost target line and then, suddenly, there is an "event" and the boost target falls briefly, and then recovers, but the actual boost falls away, very short of the target, and never recovers. When you follow the bright red line, you see where the boost target suddenly spikes downward and the actual boost follows. It is as if the ECU suddenly opened the waste gate and it stuck open.

I know that knock can cause the ECU to pull timing, but will it pull the boost target too?

Great news!

Its fixed..

It was the DV's.. Switched to Forge DV's and no more codes.

Update didn't fix it

I feel like the problem was possibly Intercooler piping, I have had three shops looks at it, the last shop completely removed the FMIC then put it back in, and it seems to be better.

Here is a 2000-6000 RPM log in both 3rd and 4th gear.

I just installed my Cobb on Saturday. I ran it on a Stage1 map for a day and then went to Stage2 Sport v301 Sunday. I haven't had any noticeable problems or dash lights but have been checking for codes occasionally and as of this morning I'm throwing the code P2DED - Power management, closed-circuit protection. Anybody know what this code alone could be, or I'm wondering if I have a similar problem to the OP and it's just a matter of time before the rest of the symptoms arise?

That is from leaving your Cobb plugged in when the car is off.

Its nothing to worry about.

Thanks for the info. I did a quick forum and Google search and couldn't find much on that code alone. Good luck with your issues.

I also got this code for leavin the cob connected!!

I think its prolly hardware and not tune related

I have had this for a few months, after reading your post I took out jb4 and put MHD tune, everything seems fine now, this is insain
