with the pressure signal pipe disconnected?

just looked. shape looks good, but looks to be offset from where you would ideally want it to be which indicates a multiplication factor of the fuelling to be out somewhere. something like the CO pot set too lean, too little fuel pressure, or possibly just an air leak in the exhaust before where the rolling road lambda sensor was placed.

get it to a proper tuner who can check your fuel pressure and fuelling on the road
