Adam, the AIT sensor is the Air Intake Temperature sensor. That is used in conjunction of the mass air flow sensor (MAF sensor) to determine how much air is making it into the engine (since air density is relative to the temperature of the air). As for the sensor location, open up your hood and look at the top of the intake near the center of the car. You should see a small black box bolted on to the intake. That is the AIT sensor. The location may not be exact as I am going off of memory for this.

Smile AT Sensor redux

There is a company called GForce that claims to have a chip for the Xtype that will gain up to 68HP. The chip according to their website, wires via two wires to the AT sensor and will reprogram the ECU. I found the AT sensor and scratch my bald head. The chip they have pictured is a normal 24 pin chip that you would find on most circuit boards and mother boards in computers. Now here is the kicker They have a list price of over $300US scratched out and a selling of of $68US plus change. I chipped a BMW I had back in the 90's and back then the chip cost over $300, I had it installed for another $150. It did increase the HP by 75 and the torque by over 100 pound feet. The installer had to take a laptop and make all sorts of changes to the ECU to make the chip work. I find this kinda fishy.

They're all fishy, you are right now where most of us X-Type owners were when we first started, we think the car should go as fast and have as much HP as it looks like they have.

Other than adding a blower or Turbo, which will spread your transfer case all over the road there are a few things you can do to safely net you a few more ponies. This guy has done a fairly extensive blog on them. http://jagmotorproject.blogspot.com/

The best bang for the buck seems to be making them breath better, adding a free flow exhaust system and a decent CAI.

Thanks for the blog site, I have to agree with you intake and exhaust probably give you the best bang for your buck.
