I have a friend with a 04 6.0 and he has the SCMT on Econo tune with the EGR unplugged and it runs great. He is going on a hunting trip this weekend where he will be going up a pretty serious mountain grade for about 5 k feet steep climb at 70 mph. He will not be towing anything, but will have 4 people and 200lbs of gear in the bed. Should he put his SCMT in Tow Safe mode or just leave it in Econo mode? He doesn't have gauges to monitor Exhaust Temp. The guy driving has a lead foot and might try to go 80 mph up the mountain so I need to give him some real safe advice not to melt anything.
In a normal situation with plugged-in EGR, would the computer command it to open the EGR while hill climbing at heavy, steady throttle in an effort to cool the Exhaust Gas Temps? Does the stock computer program even process info from exhaust gas temps on an 04?
This may have already have been answered as I have not read this entire thread. I have read that the 1704 will not adjust if you change rearends. Do you order your tuner already adjusted depending on whether you have a 373 or a 410 rearend. Also does the 1704 do anything to the transmision if you have a six speed manual. Thank you in advance for any information.

The tuner automatically tunes your truck to whatever rearend is stored in your VID block (factory calibration).
If you change gears and have Ford flash your computer for the new gears, the tuner will recognize it when you plug it in and tune accordingly.
This includes the necessary shift adjustments for automatics.
Remember that going to a larger tire AND a more aggressive gear usually does not require a correction (it's usually a wash if done correctly).
For a 6 speed manual, the 1704 VASTLY lengthens the powerband, so you can shift as high at 4300 RPM. The factory calibration STOPS making power at 3600.
It also reduces "torque reduction" making it easier to get power on demand right after a shift.
The difference in drivability and lengh of gear with the manual is incredible.

This has probably been covered somewhere in the 138 pages of this post so I beg forgiveness now.
I bought an SCMT 1704 and an MBRP Cat back system from Motorhaven and will be installing them on Labor Day Weekend along with a pyro gauge. I'm really looking forward to better throttle response and shifting.
My concern is if removing the SCMT properly will remove traceable evidence should I need to bring the truck in for a repair issue that could/would be denied coverage. The Ford sticker under the hood makes me a little nervous.
I'm not wanting/expecting a guarantee from you by any means. I would just like your professional opinion on how this works and you obviously know your product very well!
I understand if I melt down my 6.0 or Torqshift by towing in HP mode, or something stupid like that, the melted chunks are all mine and I'm "My own warranty station".

My personal recommendation is to set it to stock before going to the dealer and NEVER mention anything of it.
A P1000 or P0603 code may come up, but they come up as soon as the battery is disconnected...even on a stock truck (I've duplicated this test many times).

Hey!
I've been saying this for several years now, and Gale has said it publicly in Hot Rod Magazine" (Sept 05 issue)
Look at this quote from Gale Banks:
...."considering diesels produce roughly twice as much torque as HP, higher engine speed <than stock> can still yield more HP, even if torque isn't lowered..."
This is to the people who thought I was "silly" to do something as innovative as raising the power curve to 4200-4300 RPM!
Nothing like a long, hard powerband!

Don't mash the throttle to the floor? I don't know if you are doing that or not. By mash the throttle to the floor I mean going from a low percentage of throttle to 100% in less than a second or so.
I've found that if I feed the throttle in as the boost is building I get less smoke than when I add too much throttle too early. The difference in acceleration between the two driving styles doesn't seem to be that great.
The other thing that I do that may help is to do regular full throttle runs up the Interstate on ramps to help burn out any accumlated gunk - that a pulling the trailer every now and then helps.
