Hell yes I believe it, I've done it twice already! It feels like when you add a K&N cold air system; just a slight difference in performance... and probably more of a mental upgrade. No error codes, no pending codes.

Let's work out the logic: If the PCM is told it's running a few (and that's VERY important, if you eff-up your math and get it wrong by twenty degrees = not good) degrees cooler than it's been programmed to run 'optimally', it does what?! adds air and fuel to warm it all up; the net result is more power and a slight loss of mpgs.

I'm working with a friend to solder up a few different resistances on a few different ECT sensors and pulling with each on a dyno to get concrete numbers... to prove to everyone else what I've already realized.

A few degrees is all you need.

You can 'smh', facepalm, or whatever you want, but before you quickly brush me off as insane; do some thinking!
1)The sensor detects a range
2)the real-time 'measurement' is reported to the PCM
3)based on it, and other sensors, the computer reacts to change a/f ratio to suit for the optimal setting in the stock maps (STOCK MAPS, a tuned car is different, and a different conversation!)
4)a cold engine creates more NOX and other pollutants, Ford engineered efficiency into the system for emissions sake, not power
5)because the actual temperature is normal, nothing detrimental is occurring inside the engine
6)because the signal sent from the ECT sensor is only a few degrees off, the PCM doesn't make a radical enough change to hurt anything

-it just allows a little bit more air and fuel into the equation-

It'll free up rotating mass, which makes it rev up a whole lot faster than stock... I did it a few years ago, and the difference is night and day! It usually scares someone that's not expecting it.

The computer has nothing to do with adding air. That's done by the throttle body.

And also if you put a potato in the tail pipe the exhaust will build up enough pressure in the cylinder to where it compresses the air and builds boost. Waalla...boost without the hassle of the turbo system.

True facts on the throttle body, however fuel trim is computer work. If you add more fuel, it cools the burn in the cylinder, which gives you more power.

I think it will just run rich, but if you can show it works then awesome.
