Yes, I think it should hit 1 bar around 3000rpm.
There's some power hiding in there somewhere, I just wish I could find it!

For a reference: I have basically the same mods (w/o the MAF: not yet installed) My Zietronix shows 1 bar at about 2800 rpms... (not yet datalogged)
Note: my K26/6 doesn't hold the boost to redline, not even close...but I'm ready to replace the diverter valve before summer and hopefully fix that!
