IAT placement

[Jared Tschetter]

I would agree with grumpy, one of the 4gen f-body tricks is to move the iat
further to the front of the air stream to keep it as far away from the heat
soaked TB as possible.  The air might not be any cooler coming by, but if the
sensor is hot already it might skew the results.
