Why did my Dad's 05 expy beat my 05 FX4
 

I have a 2005 FX4 extended cab. My Dad has a 2005 expedition. Both have same engine, 5.4 3V. He had like six people in his truck, and I had only me and my wife. From a dead stop, we were even until about 35 or 40 then he just starts pulling away. He also gets better gas mileage than me. I average around 12, if I'm lucky. He gets like 14-15. Why? Gears would not make that kind of difference in power and gas mileage. My truck runs OK, but sheesh.

I had a 2000 expy 4 wheel drive, traded it on my new 07 fx4. I think it was just flat out quicker. I think alot also has to do with how they are geared too.

He has a 6 speed tranny...less power loss, better power band. :thumbsup:

My 2005 FX4 was a dog compared to the wife's 2006 Expedition. They seem to be programmed differently because they both sported a 3V 5.4L, 4-speed tranny with 3.73 LS. My 2007 FX4 will give her Expedition a run for its money (same power train). She's quicker 0-35, but I'll blow by her after that. We both get 15MPG in mixed driving.

According to Ford's sale literature, the F-150 is programmed for a slow and steady take-off to avoid the neck breaking herky-jerky acceleration found on other makes of trucks. The slow accel is annoying at times, but I've found it very pleasant when towing.

It even feels much stronger when I drive it, With 7 people in it!!!! This really hacks me off. It's a 2005 also. Why would Ford put a 6 speed tranny in the Expy and not a half ton truck? I expected that it had something to do with the calibration in it.

:confused:

You should let him win even if you are faster, he's your dad for crying out loud.

You gotta know he let you 'win' plenty of times when you were a runt.

Get an xcalII

yep time for a programmer.

How much do you and your wife weigh?:D

You sure it's a 6-speed tranny? Book says they're 4-speed.

Expy
 

Expy did not come on a 6 speed on that year...

I disagree. Looks like dad dropped in a CAI, custom tune, and a set of gears behind his son's back so that he can smoke him. :lol: :lol:

I wonder if the ford dealership could flash my truck with the same program for a 2005 expy, without causing any problems?

Yep it has a 6 speed.......4 speed trans + hi and low 4wd = 6 speed. LOL!!!!


Worland, your right on....should be a 4r100(4speed) if memory serves me correct.

Just have Rousch do a little tune job on it for you, like maybe a Stage II. Then you can blow everyone's doors off. Nothin' about $10K wouldn't cure!

:cool: :cool: :cool:
