    Hi Tim, sorry the MAF didn't help, Ill have a look around and see if I can find something that would cause the power cut. If you have some time this weekend I would be happy to have a look at your intake, and we could check some of the hoses, etc... try a different tune using the Acces Port (stage 1 tune) and see if that fixes it.

    Had a mate look at it after the gym and be seems to think it could be a tps problem As its mainly noticeable at specific throttle position.

    That looks like it could be the case, just reading up on it and in this forum thread (different car) it sounds like what you described. Signs And Symptoms Of A Bad Throttle Position Sensor On A Mazda Mx 3
    Knowing how to fix it is another thing, once again happy to have a go, if anyone else has had experiences with this it might pay off to get a second opinion.

    I have read somewhere that the Electronic throttle bodies don't use the standard potentiometer based TPS systems of cable based systems, it is more of an its either working correctly or not at all scenario in the electronic TBs, rather than risking the chance and potential dangers of erroneous reading from a faulty sensor, also because the ECU is controlling the throttle plate angle, not the user, it knows how much fuel etc is reqd due to TP angle, AFR, load etc.

    Best way to check the throttle plate would be to try logging again with an AP and compare requested vs actual throttle positions
