Quick Question

[Whitelightning74]

Ok guys I am new here and just bought my first diesel last week. Its a 05 f-250 HD series. I love it so far. I have a question regaurding the power of these trucks. I have never driven a diesel until now but this thing amazes me with its power. You can be kreeping along and kick it and when the turbo kicks in it will spin the wheels over. I basically am trying to figure out if this is something these trucks do stock or could it have a chip. I mean its nothing over whelming but it is impressive for the size of this truck. It dont smoke black smoke like the rest of the trucks i seen with the programmers/

Stock the 6.0's are pretty impressive. Most 6.0's I've seen that are running a chip or tuner smoke pretty good. I think it is safe to say it is stock if you are not seeing smoke, Although i'm no expert with the 6.0's.

the 6.0 will break them loose pretty easy you probly dont have a chip unless you notuced the tranny shifting differently. its probly not chipped up

Welcome to the site!
'HD' series?
Anyway, I have an '05 4x4 crew cab. It now has a 4" exhaust and an improved intake elbow on it (no power control mods). Even before this, I had plenty of power. I wouldn't be surprised if yours is still stock. These 6.0's are pretty strong straight from the factory. It could, however, have a module or program installed. You would have to know what to look for (module) or hook up an analyzer to tell (program). If you don't have additional gauges (boost, egt) you might want to find out for sure if it has been modded, because the mods can significantly increase exhaust temps, which can in turn can cause you a surprise meltdown ($$$$$).
Congrats on your rig!

ok just got back from the dealer and he showed me a switch that I have not seen since i had it. lol/ Its a three way toggle switch and in the up mode is were its been at since i bought it. The middle is in between power I guess and the last one is the most power cause it smokle alot . My question is were do I look to find out what i got and were should I run this thing at for normal good fuel mileage. Should I stay away from stage 3?

I'm not sure what you have - kinda' sounds like a Quadzilla adjustable module (or equivalent). Start tracing the wires back from the three-way switch. You should eventually get to the module. The Quadzilla is a bright green cube.

Can anyone explain the proper way to activate this. is it ok to switch this on during driving or should it be done before the engine is started. also is it safe to use this on the hightest level?

[MrJohnWayne]

Don't know about switching it. I would suggest adding some gauges (specifically Exhaust Gas Temp - EGT) before running on level three. Other than that should be no problem running it wherever.

If you do not HAVE GAUGES U NEED THEM YESTERDAY !!!!!
I run my truck by lookin' at my gauges ONLY...
I Monitor
EGT (Exhaust Gas Temp)...........!!!!!!!!!!!!!!!!!!!!!!
Tranny Temp.
Boost in PSI.
Fuel Pressure in PSI.
Coolant Temp.
Oil Temp.
Intake air Temp.
I say this from EXPERIENCE
I Burned up mt OEM Turbo on my 7.3L
Then Proceeded to LOOSE oil Pressure and ended up needin' a Complete Rebuild..$$$$$$$
Get Gauges and Hope and Pray that the previous owner has not done too much damage already. If you do not MONITOR your Engine Parameters you will be destroying parts you are unaware Of....
Just my Opinion........Good Luck and Welcome to the site.
