thanks for your response,I did check live data the baro sensor is showing 3.7 hg and not altering.the boost sensor is approx 30.00hg 1.2volts at idle,rising to approx 60.00hg 4.0volts on boost whilst on road test.I was stuck for info as to what i should be seeing,but from data recieved from boost sensor it appeared to be working ok.i did disconect boost sensor and it flagged a fault code which i then cleared.I am suspecting baro sensor or wiring fault ? I will keep you posted.


Thanks Mark.
