Sorry, missed the question. Where do you have your IAT sensor installed? Also, the IAT sensor on the OEM hat is a push and turn and locks the bulb in a specific direction. I think your air tube is plenty large enough, but is the filter free flowing? Putting too much oil on the filter can restrict the flow. Is the air tube heat soaking the incoming air. Do you have a power wire installed? Lowering the IAT sensor signal either by lowering incoming air temperature (the best) or adjusting the IAT signal voltage (pwr wire) will slightly advance ignition timing. Good luck and let us know what you find.
 
Greg, the sensor is mounted in basically the same position and direction as it was in the OEM part. The filter is a K%N cone that is new and as you know come factory oiled. Not sure what your talking about on the power wire advancing the timing....haven't heard of that one before. With the heat of the engine especially the elbow at the TB warms up and does get more pliable than the factory tube. I will put a few more miles on it before buying another PVC elbow to replace the flexible one that came with the kit.

As you know the IAT sensor signals the PCM the air inlet temperature. The sensor is a basic thermistor, increasing this value by adding a resistor fools the PCM into believing the air temperature is cooler than it actually is. When the PCM senses cooler inlet air it advances the timing to better utilise the expected denser air. This adds some timing and possibly some fuel when running in open loop (wot). I have mine set to read 20 degree cooler than the actual inlet air temperature. Good luck..
Edit: if you look at my picture you can see I insolated the entire tube and air box in an attempt to keep the inlet air from soaking up engine bay heat.

More editing: Did a little research and found the ECT function the same as the IAT and uses the same sensor voltage range. This would indicate that the same logic can be applied to the ECT as to the IAT. In other words it would be possible to use a pwr wire on the ECT and gain the benefits that are being seen by actually using the 170 degree thremostat. I see advantages in actually lowering the engine temperature to 180 range, but would like the added timing of the 170 temperature. This can be achieved by using a resistor same as the IAT pwr wire. Thinking out loud...

And FLRamSport, where did you get your engine cover from?
