It comes with an economy tune, a towing tune with 2 HP settings and a performance tune. Along with all of that you can play with shift points and firmness, idle rpms, correct spedo for tire size and gear changes...all sorts of goodies

They both come with the preloaded tunes however i dont believe the SF3 has the ability to store the custom tunes. The X3 will disable the EGR valve for sure and i would be willing to bet the SF3 will. I have never played with an SF3, nor can i remember running across anybody here that has one. The X3 seems to be the choice for most people...havent had a problem out of mine yet.

that isn't correct the x3 does not disable the egr nor block any codes in stock form
that is custom tune territory ,
the SF3 is the predecessor of the x3 and can store tunes and has canned tunes as well

Yea, as i said before i haven't messed with the sf3 at all...thanks for the correction, i hate to spread bad information. However under the strategy tune section when you select adjust options on the X3 there is an option that says EGR where you can select on or off. My EGR cooler is deleted so i have never messed with it. Also on the SCT site it says that the SF3 supports up to 2010 models which would make it seem not to be the predecessor...from what i have read on the page you posted, the difference between the two devices is that the SF3 retains the tunes that come preloaded and 3 custom tunes, which is not what SCT says on the site. However i am not and have never claimed to be an SCT expert. Would be interesting to see why it has EGR function but possibly doesn't work, maybe it just a function for a different type of vehicle???

go plug that puppy in! then see if EGR is an option when you go to load tunes,, you can always abort at the last minute ... or improve your truck tremendously with even a canned tune ! if warranty is an issue or real concern just go back to stock and clear the PCM the next day no harm no foul IMHO

The EGR function is on the same page as the tune type function...whenever you go to change tunes under the options menu you choose the tune type and then any of the functions i listed above. As i mentioned earlier my EGR cooler is plugged so the EGR valve function would do me no benefit. My valve still functions normally, however the exhaust inlet on my EGR cooler is plugged.

well you think it would still throw a code maybe not a CEL ,, but most folks just unplug it ,, and then the stock SCT tune won't block the CEL as far as I know
ps My AE and insight will pull codes the SCT doesn't show ,, specially the EGR related ones
