Haven't noticed anything straight away.

Since fitting the new MAF, I have tried a few 0-100 times. Straight up it only managed a 10.5sec, then after about 10mins driving it did a 8.8 (about factory time).

One thing I'm not quite getting is that I tried the 0-100 again, first go only did a 10sec, with the throttle flat. Then I tried again with the throttle only held down until the kick down switch (without activating it), it changed gear earlier and did a 8.8 again. (In 27deg C ambient temp too).

So it feels like it is holding gears way too long with the throttle flat.

Does anyone know why it would be doing this?
