    Hi. First sorry for my bad english [emoji12].

    I'm doing tests to check my low performance on dyno. 187hp instead of 204hp (1997 2.5 Boxster). No cel, new lambdas, new filters (all), no dtc.

     

    I have all values correct except:

    -Spec. Air mass: 14-16 instead of 15.25-15.75

    -Spec. air adaptation: -1 instead of 1.45-1.55

    -Ignition timing: 4.5-5.3 instead of 4.8-5.8

    Maf readings are correct at iddle and at 3000rpm. Peak maf readings 2nd gear WOT are about 550kg/h. Tried with another used maf and same values at wot 2nd gear.

    AOS? Air leak?

    P.S.: installed high flow headers, 996 3.4 throttle body (correct tps readings) and a plenum insert like techno torque.

    Plenum insert:
