Thinking about an SCT

[kkonen]

I am considering purchasing an SCT programmer. I have two motivations: adjusting for tire size (planning to buy 35s) and improved fuel economy. Do I need a EGT gauge?

I usually drive like a grandma.
I don't pull a trailer very often and don't anticipate pulling anything over 5-6000 lbs.

Currently, my mods include 4" magnaflow turboback with test pipe and intake elbow. I plan to do an intake and zoodad. I have no other goals with the exception of a programmer.

Any other advice is appreciated.

1. yes get SCT
2. get custom tunes from dj's, innovative, etc.
3. yes u do need EGT gauge... turbo boost and tranny temp if u want (though it doesnt sound like u need it)
4. if u get the chip drive ur truck hard once in a while.... diesels are supposed to be run hard.
5. other people will chime in with their opinions so take it all in and do a little research before making any decisions...

Good Morning,

We do implement your gear ratio and revolutions per mile in all your tunes which helps with tranny shifts and further customizes the files for your truck but the SCT will not correct your speedometer.

I see that is one of your reasons for going with a programmer and thought I'd let you know. However, as far as economizing you will gain mpg with a custom tune. I received this statement in an email yesterday:

I actually towed with the street with jake brake over the weekend and it worked very well. I gained 4.5 MPG over no XCal3 by Barry

As far as an egt gauge, if you drive like grandma and don't tow heavy you'll be fine with our files without an egt gauge. Gauges are an insurance policy and are very useful but in some cases they would be more of a luxury than a necessity.

Thanks,
Vivian

+1 If you don't drive hard you shouldn't worry about gauges, but the skinny pedel tends to hit the floor when you get a tuner.

If the SCT doesn't recalbrate the speedometer, what is the best way to do it? Is it a dealer thing or do I have to buy a different calibrator?

The SCT website is not clear that the speedometer is not corrected. Since it says you can input tire size and axle ratios, I assumed it corrected the speedometer. Quite annoying.

That's an understatement

I've heard a TruSpeed works well to recalibrate the speedometer. I've also heard Ford has a flash but I spoke to a gentleman yesterday who said his dealership didn't know anything abou it.

Thanks,

I think the dealership can adjust you up to 35 inch tires.

These folks have guided you well. The only thing I would like to add is that unless you are planning on adding injectors and other higher HP mods, the stock intake on the 6.0L does an adequate job for what you are needing. Oh and btw, watch the Grandma comments! Good Luck in your search for power and mpg!
