Being an old fangled carb guy, who can set ignition points with his eyes closed, I may be a little confused but it's my understanding the new computer controlled engines add another piece to the puzzle.
It seems I read the computer controlls the air/fuel mix and is designed to work with the engine during a wide RPM range. That includes all the design features (or failures) built into the engine.
To see the maximum affect of changes (including a TB spacer) wouldn't you also have to tweak the computer software?
I'd think the whistling was from a vacuum leak and not the "vortex" of the spacer. If you are experiencing a higher rpm, this may be why. Of course, as Aekisu pointed out, the computer may compensate for the leak by changing the fuel/air mix... but it can not fix the vacuum leak sound...
just my .02

Aekisu, Yes your right, You can't realize the full potential of the motor, unless you can change the air fuel ratio and timing. Whith these motors that can only be done with a chip or program.

The biggest problem with any sort of "whistling" noise... that is generally assosiated with turbulance, which doesnt equate to increased HP when that turbulance is anywhere in your intake/ports of your vehicle.
HELLO,
TODAY I REMOVED MY HELIX POWER TOWER, MY TRUCK DOES BETTER, WITH THE POWER TOWER, FULL THROTTLE IN THE SAME LOCATION, I TESTED MY TRUCK, IT BARKS THE TIRES AND AFTER REMOVING THE POWER TOWER, I TRIED MY TRUCK IN THE SAME LOCATION, ANOTHER TRIAL RUN, THE TIRES BARK LOUDER, I CHECKED IT OUT ON THE ROAD, IT SHIFTS A 88 MPH INTO THIRD, MY TRUCK IS SMOOTHER WITHOUT THE POWER TOWER AND A LITTLE QUIETER. THE BEST HELP WAS TWO STAGE 4 FLOW MASTERS A CROSS OVER PIPE, AND THEN I REMOVED ALL THE FACTORY AIR INTAKE AND REPLACED IT WITH THE K&N SYSTEM, THEN WENT WITH HYPER TECH III, THIS TRUCK WILL GET UP AND GO, I WANT EVER WASTE ANY MONEY AGAIN ON THROTTLE BODY SPACERS, A CARB. OR THROTTLE BODY INJECTION, MAYBE IT WILL WORK, BUT NOT ON THE 2004 F-150.
Hey everyone, I want to install a TB spacer on my 04 F250 5.4L 4x4. I was wondering if anyone has installed one of these and do they work?? I can't find one for an 04 but they list one for an 02, are the TB'S the same on these two years? Thanks in advance for your help.

PLEASE DON'T WASTE YOUR MONEY, I TRIED THE HELIX ON MY 2004 F-150 5.4 ENGINE, MY TRUCK DOES BETTER WITHOUT IT. I HAVE BUILT HOT RODS OVER THE YEARS, MY TRUCK HAS TWO FLOW MASTERS, 180 DEGREE STAT, AND I RE TUNED IT WITH THE HYPER TECH. IT RUNS SO WELL, AND AT FULL THROTTLE IT BARKS THE TIRES WHEN SHIFTING TO SECOND, (4 SPEED AUTO) IF I DRIVE IT 68 MPH I CAN GET 20 AND BETTER, OVER ALL UNDER GOOD DRIVING PRACTICE , MY MILEAGE STAYS CLOSE TO 20 AND OVER 20. WHEN I PLAY WITH IT, YES THE MILEAGE DROPS TO 17 AND HIGH 16'S, FULL THROTTLE, IT SHIFTS OUT OF 3RD INTO 4TH AT 120 MPH, I'VE SAW ABOUT 120 PLUS MPH, I ONLY DID THIS ONE TIME, THE TRUCK WILL GET UP AND GO. I USE SYNTHETIC 5W20 OIL, AND I HAVE USED ROYAL PURPLE. THE ELECTRONIC THROTTLE WAS LAZY WHEN I FIRST GOT THE TRUCK, THE BEST WAY TO FIX THIS VERY QUICK, IS TO TURN ON THE IGNITION, DON'T START THE ENGINE LEAVE THE IGNITION ON FOR 5 TO 10 SECONDS AND TURN OFF THE IGNITION AND LEAVE IT OFF FOR 5 TO 10 SECONDS, AND WHEN YOU START IT, THE TAKE OFF IS MUCH BETTER, I WAS TOLD THAT BY DOING THIS THE THROTTLE POSITION SENSOR IS RE PROGRAMED. I JUST BARELY TOUCH THE THROTTLE PEDAL AND MY TRUCK TAKES OFF VERY NICE.
I just put an Airraid on my 5.4 F150 FX4. I'm noticing a strange whistling sound at diff rpms. Checked all connections for a leak but found none. Salesman said it might do this because of "vortex". I don't know for sure. Seems like it might have helped @WOT.
TAKE IT OFF AND YOUR TRUCK WILL RUN BETTER, I HAD ONE ON MY 5.4 F-150.
TB spacers are expensive paper weights. Even if you get one with a "helix bore" or whatever, the airflow pattern will still be the same by the time it actually passes through the intake plenum.

+1. TBS's are the same thing as a Tornado in the intake. They both claim to create some sort of swirling vortex in the intake, and they are both worthless garbage. Like skaterbro said, even IF they created this vortex, as soon as it reaches the intake manifold, it gets all broken up as the air moves down the individual runners. The only time spacers work is on carbureted and throttle body injected engines. They work in these applications because the fuel gets mixed with the air, THEN through the spacer, which gives the mixture (not just air like on multi-port injected engines) more time to mix thoroughly and then goes into the engine. On a multi-port injected engine however, you have only air going through the spacer which does not create a better air/fuel mixture, which is the whole premise of this device. Also, like I said before, by the time the air gets mixed with the fuel, the vortex has been disrupted and destroyed by the intake manifold.

Needs a lot of work, including some rot on the body, but shes getting there.

No, you don' need to tweak it to see a benefit, but you can get additional gains with a tuner. The EFI system is designed to take into account a wide range of engine and environmental conditions. The computer calculates the amount of fuel required to supply the air passing through the motor realtime, and there is a fair amount of over capacity built-in to the system, so it will compensate for an increase in airflow through the motor.
As others have inticated the TB spacers are generally of no benefit on multiport EFI motors with tuned runner intakes. The only motor that appears to benefit is the EFI 460, and not surprisingly it uses a modified carburator intake with a relatively small volume throttlebody adapter. This just under scores the point that this intake is undersized for the motor, but this is not the case with other Ford motors.
