hi, just an update to let u know how the testin of this got on. the throttle body has been on a friends cars for about a month now, which was driven every day. he said it feels more responsive, but not much if any extra power, but also said that when driven sensibly he was seeing a couple of extra mpg!! which i wouldnt of thought to be honest. all in all he was happy with it. no complants any way, well just one which was,in his words, "your not havin it back!!" now alls ive got to do is get this vr6 into my mk2 and test it for my self. thanks rob
