Nice rant (problems at home???
)...Well the expodition is bone stock, I'v got a cheap e-bay special dual cold air intake, and a superchip Flashpaq. Just got the Flashpaq last night, running 89 octane on the 87 Tune, will probably switch to tow/haul run 89 Octane and up the shift points...1-2 6000 and 2-3 5900. $$

the 5.4 is a dog, off the line the ford bites hard, quicker than the hemi, after the first twenty feet the ram is quicker.
Its all on the rear end gearing, the hemi with a 392 is a tire roaster, no potential for traction, the 5.4 3v ford with a 355 or 373 is feared for torque at low Rpms, some where betwean 1200 to 1500 Rpm is where the ford 5.43v is maxing out in torque, the variable valve timming really helps the 5.4 3v out in low to mid range torque.
The hemi maxs out with h/p and torque numbers higher in the rpm range, not sure on the exact specks, but the ford will getting a awsome view of a dodges behind, real quick.
I had a 5.4 3v in my 04 F-150, Dam thing never run right, cam phasser issues, electrical sytem would just randomly die out, and it was harder on flue than my hemi.

Not to play devils advocate, but my brother in law had an f150 with the 5.4, with a nine inch lift. he had it regeared to 4.56's, and it would run pretty damned good with his hypertech.

Mine has. The 5.4L is a dog, I've beat F150s with my truck, Expeditions are even heavier, a Hemi Ram should embarrass him quite badly.
And Feej is right, Superchips Tow tune requires 91 or higher.

Yup, you fellas are right it is 91 Octane for tow/haul, Thanks.
The two of us are both off work this week, if he doesn't back out I'll take his cash. I'll keep you updated. Gonna be a busy week putting the engine back in an 85 mk1 mr2, very small car. you don't really get in it you kind of just put in on....hehe
