    No boost no power

    My 2008
    KAWASAKI UOLTRA 250X
    His jet skis without power
    on the instrument panel is unable to rise above 6 psi OF BOOST
    I did test the blow off valve relieves pressure in idle mode too full throttle even when I took out the Vacuum tube
    and his continued to vent air
    I connected a external pressure gauge to the manifold and reached at full throttle to 15 psi
    after closing the blow off valve i could not rise above 6 psi pressure on the gauge of the Jet
    air pressure sensor checked by air pressure much more than 15PSI and still was 6 psi
    I understand that air pressure sensor is bad and need to replace
    What do you think need replacethe blow off valve I do not think he need vent on this mode
