    You are correct with your theory. Also removing them completely allong with the bar will reveal the extra mpg and torque.

    If you plug in the motor somewhere in the engine bay then it can't throw a code due to the motor still functioning, it can only sense pulse, and not pressure, so it can't tell you have removed the rod. I've done a few now for different people and not seen a mil light or any codes. You will be...

    The space required to get a tap in is to small. I would imagine thread lock would survive (221). But couldn't be 100% I wouldn't worry,

    SURELLY you could buy one from a breakers yard? They are on eBay uk all day for $80 I would not recommend plugging the centre voids unless you can 100% guarantee that you can get each hole sealed and flush with each inlet wall.

    I will agree with storx on the us tuning, with a country so vast you would expect more people pushing the limits. Tuning diesels has been very big in the uk for over 10 years now, I personally owned and built the only 220bhp ford mondeo st tdci 2.2 last year. I took it round silverstone...

    Storx that's one of the little traits with these engines, basically as the flaps are opening and shutting at different times dependent on inlet pressure it will effect the way the car runs. Hence me putting in my first post that removing the flap system also removed all the nigly traits aswell

    Apologies to those that are still awaiting pics and details, my Internet is down at home so can't access emails, Regarding mods to do this, I recommend doing this regardless of tune, I'm aware the manual states open or shut details of what exactly the flaps do. And to be honest I think it's...

    Just unplugging it and leaving flaps in situ. Will cause the above probs due to the gasses getting drawn against the flaps. Removing the whole lot of junk completely is the only way forward
