power wire?

[BLKDODGE04]

anyone tried the power wire on the 4.7 and noticed any difference? i tried the homemade version with soldering the 4.7k ohm resistor in line of the iat sensor wire and i didnt notice any difference.

I ran one for 4-5 years but it was mostly to compensate for running long tubes.
Took it off when i added a 180 t-stat.

EDIT: oops sorry i did not realize you were looking for 4.7 owner experiences.

Bump for ya, I'm sure there will be a difference, but prolly nothing you'll feel by "seat of the pants"

is it supposed to help with fuel mileage?

Found this:

They give an extra boost at wot, and ''supposedly mpg's ,
It shows a lower air temperature than what is actually being sucked into the motor,making the pcm admit 2% more fuel than normal. It does not hurt the motor in anyway and can be removed for epa testing.

I was one of the guys that first tested the power wire when it came out. It tricks your computer into thinking that the air coming into your engine is 20* coller than what it is actually reading. This causes the computer to feed your engine a little more fuel. I tested this at the track and on the dyno and never saw a positive or negative gain from it. Only thing that changed was that my mileage actually went down instead of up.

thanks for the info, like i said i tried it and never noticed any power gains or fuel mileage change

Ok, so you "trick" the computer by changing the perceived air temp. The computer has a table for fuel requirements at given temps, and adds a few percent more fuel. What stops the o2 sensors from reading the rich mixture and compensating by shorter fuel injector cycle rates?

The most notable change I noticed in my 4.7 was the aFe followed by the Super Chip program. I never look at MPG. Ever. Throttle response and acceleration is what I wanted. I got it. I dump 93 octane in the tank and roll away. I'm a happy camper.
