I was always led to believe that the SCT’s were the way to go. I have no experience with any other brands, and I didn’t even buy my own SCT, the place I bought my truck threw and X4 in when I bought it. I only run the canned tunes, most often the trans only tune. I also like the way the interface is set up.

 

I also heard a lot of good things about SCT so I went with the X4. It's still fairly new to me but so far it's worked great. I don't use it for a monitor. Still using my ScanGauge for now but that might change.

 

Have either of you noticed an uptick in mpg?

Still to be seen. I literally have been running it on a custom tune for only a few days.

 

SCT with custom tunes from quick tricks (my trucks preference), gearhead, truck source diesel or innovative #end of thread [emoji23]

You purchase tunes from them and upload to the scanner, I assume?

Yes they will build then to your truck and what your wanting to use it for.... Vivian and Eric at quick tricks have Awsome customer service and tunes

I've noticed an uptick in MPG, but i can't isolate it to the tuner. I did a bunch of maintenance all at once after I got it and the MPG improved 3 or 4 MPG from 15 mpg to 18.5-19 mpg.

 

My main goal is to have a tune that provides max mpg, but switch to power when I need it. This is why I asked. None the less, whatever you did worked.

Is there a reason you run the trans only tune?

We got the Bully Dog tuner and I'm pleased. I can't give you comparative performance with other tuners, though, or before/after diesel mileage since we bought the truck and took it pretty much straight to the shop for bulletproofing. I will say that the Bully Dog seems simple to use, gives clear feedback, and it's nice that we can set a driving mode (trailering, performance or extreme, as I remember) then disconnect the tuner. I just have to reconnect it and change the mode when I go to pull the trailer.

The shop told me, when I was debating the tuner, that they've often offered to install it, then take it off and give the money back if an owner didn't like it. Never gonna happen - I don't know if it's a result of the 4" pipes we installed, but this thing accelerates and sounds like a drag racer! And that's on the Performance mode, which is the better mileage mode. I've never had a pickup before so I don't know what's normal, but this thing is a long bed king cab F-350, a big truck, and with this tuner the thing makes you smile if you need to step on it. So - a tuner is probably a pretty good investment and I'll bet you're happy with whatever you select.

What mpg are you getting?
