Default car is doing what it felt like it was doing.. not even requesting boost until nearly 4k rpms. ideas?

<img src="http://i291.photobucket.com/albums/ll300/raktar/rpm.gif" />

The line that starts highest on the left side is the RPMS. At the cursor (where the red line is), RPMs = 3775. just to the left of the cursor you can see the dark green line (boost request) FINALLY start to climb above ambient.

why on earth would it not be requesting boost until rpms are almost 4k?

Default may not be related, but the throttle body doesn't go full open before then.

got any codes?

Default maybe just an error between ECUx and ECU, not necessarily a problem?

guessing here.
