Coming to a stop, I feel like I am bumped from behind

[Tn4x4]

The bumper is a custom job. I'll get it to paint tomorrow and try to post some pics when it's all finished. There are a few other pictures on the thread "New Shoes for My ST". I found only 1 source for a winch mount and I decided I wanted something a little "sturdier" so I began working with a friend who owns a welding shop. The winch is a Warn 9000 and I still have my regular battery at the moment. After paint, I'll mount a couple of KC Daylighters.
You can grab the bumper or guard at any point and shake the whole truck. It should be "tuff enuf".

You should post pics of how stuff is wired to battery. My battery cables seems to prevent me from wanting to add accessories to battery.

I apologize for the hijack - any comments on my bumper/winch should be addressed in the thread titled "a new winch mount" which I posted this morning.
Thanks!
And THANKS for the tuning information. After my mods, I need a little more grunt.

Torrie from Unleashed Tuning did mine. Yes it was a BIG difference, like power on demand, you don't get that sluggish laggy take off, and the shifting is very noticeable, shifts hard between gears! Especially when you change it back to stock, it feels like a 4cyl!

The factory setup limits your standing acceleration/takeoff, gives you only like 60-70% max throttle until you start to move and it'll gradually increase as you go, hence to make smoother take-offs and makes the drivetrain last longer. Thats why if you're moving and going about 15-20Kph and then floor it you'll notice a harder takeoff then standing still because you're moving and the system will then give you near full throttle, just limits you're takeoff from stop, and also softer shifting for smoother shifts.

Thats why it feels unlike a V8 compared to normal vehicles at take-off because of this limiter!

ALSO don't forget to reset your OIL Life %, since when your OIL LIFE becomes less than 10%, it ALSO limits your POWER to about 75-80%!!! I know this because this had happened to me and as soon as I reset the OIL LIFE % it instantly got all the power back! From factory it does this so you don't run FULL power on dirty oil, so your engine can last longer!

All these nifty perks from Ford to make the engine and drivetrain last longer is cool, but most ppl don't know about this and are surprised when it seems not as powerful as they might think!

Now with the tune, it removes these features (except for the OIL life power limiter), giving you full 100% throttle at takeoff and with the transmission tune makes it shift alot harder and stays and shifts between gears alot better while accelerating. Plus the tune also changes your timing and spark and type of fuel and give you a little more power and torque too!

My 3 custom tunes are as follows:

Tune 1 (Economy 87) - Tunes engine to use better mileage using normal gas
Tune 2 (Performance 93) - Tunes engine for most power using 93 octane gas
Tune 3 (Performance 93 with ABS off, Traction Control off) - Tuned for Drag Racing at the tracks!

I mostly use Tune 2 all the time, and only use Tune 1 if going on long trips, even then so far all tunes gives me better mileage than stock if I drive it conservatively... which hardly happens, that instant torque rush feeling is all TOO ADDICTIVE!!!

I also have this combined with my K&N CAI and Thrush Turbo Welded Exhaust with Resonator Delete)

I say its definetely noticeable! It should have been like this from factory! Now it feels like a V8!

Thanks for a great reply!
I have a SCT tuner which has tunes for my F250 V-10. I didn't know about Torrie when I bought it but I think I can use the same device?

As long as its the X3 3000 model or any model compatible that can hold custom tunes with the sport trac, and its been unlocked, he can tune it for you!

The SCT livewire thou does not do the transmission tunes...

SCT X3 3000 (Perfect!)
SCT TSE (Perfect!)
SCT iTSX Wireless (Perfect!)
SCT Livewire (Does Engine Tuning, but not transmission tuning!)
