Well it looks like to me they tuned the low end and didn't really change the top end at all.
How is the boost holding? Are you have any problems with boost creep?
How was the A/F ratio? I will guess they cleaned it up, from what I have seen on other Cobb AccessPorts.
Also what is happening at 5300? Is it detonating, hitting some sort of limit? In any case it doesn't look to smooth? How does it feel on the road? Remember they are not based in Cali and have to make sure it runs safe. I would call Cobb and talk to them and see what thier suggestions might be. They might have a easy solution for you.
Here is a tune that is a lot smoother and probably a little closer to what you would want to see out of a dyno run, not the HP, but the curve, and smoothness.

hey guys.
My .02 The 275 ponies and 300+ lbs is coming from 91 octane. If we dyno it with 93 octane (like how the stock STi come and how Vishnu's number claims) I'm sure it's higher.
The 350 hp claim by Cobb is probably 93 octane.
275/300 lbs sounds about right with just a high flow cat turbo back and AP. Otherwise, the car should be bone stock. Right?
