SCT Xcal2
Howdy, new to the Forum, I have an Xcal2 that I bought for my Mustang, traded off the Stang, local shop told me they can reprogram the Xcal so it will work for my truck (04 FX4) for $150.00 does that sound reasonable ? My truck is totally stock, I just towed a 4 place ATV trailer over some pretty steep hills on a trip to the Desert, got 21 MPG, which I think is great, what would I have to do to get any better milage ?
Wow, great welcome, sorry if I haven't spent a bunch on mods and still get crap milage, but that is what it got !

I'm getting 13.5 average with my mods, but even stock my best was 15-16mpg with 3.73 gearing
.Was the trailer loaded, also what gearing does the FX4 come with?

As far as the XCAL2, just give Troyer a call and they will get you all lined up!

I had a full tank of gas when we left, 36985 miles, I gassed up the next morning after we got back, 37214 miles, that's 529 miles right ? I put 24.919 gallons of 87 Octane in, close enough to call 25 gallons, 25 into 529 = 21.16 I will check the next tank, it will be mostly around town driving so I expect it to be lower, and I do have the 5.4 engine.
