On the dyno mine spiked boost at 11psi but then went back down to 9psi - I'd never noticed this before on my boost gauge (but then again I'm not staring at the boost gauge for a great deal of time whilst at wide open throttle). I'd say a similar thing is happening to yours. You are running a haltec and not the original ECU? I'd expect the original ECU to run very rich at higher rpm at std boost (mine did)or even higher boost. Either your map is not right for the engine... or it could be that you're running the stock 1jz MAP sensor. Apparently this has a max limit of 1 bar so if you were over this than you'd be getting no increased signal from the map sensor as the boost went up to 16-17psi and the Haltech may not be adding more fuel for the incresead airflow over 1 bar.
