Got my Atlas 40 last month and if anything getting a touch worse economy. Don't notice any increase in power, cleaner acceleration though.
What I really notice is that we live up a fairly steep climb. Before I had to get to way over 60mph at the bottom and feather the throttle near the top to stop the box from changing down. Now I can do the whole lot at a steady 50mph in top gear. More low-down power?

I have the atlas 40. I didn't get better MPG's they stayed the same. I did get better throttle response. I also have higher EGT. Pulling a trailer I have to really watch my gauge!!!!
that's the part I don't like. Even getting on the pedal it gets to 1300 real easy and I really don't like that

I'll chime in here and say (again) that I'm one of the ones that didn't get a whole lot out of the Atlas-40. It didn't get worse, but then again, it didn't get better. I also started with a known-good FICM.
But if you do a little scratching, more often than not the folks who don't see anything out of it are late-build '06's and '07's. We've known for several years that these later engines just don't respond as well to tuning as the earlier engines (and strategies) do, even with PCM rollbacks to earlier '06 and '07 strategies.
What's interesting in my experience is that I didn't notice much of a difference in performance until I started loading some OLD custom tunes I had laying around on an old computer. The mileage didn't change, but the part-throttle tip-in performance was, while not substantially better, actually noticeable; this is saying something for the '07's.

When I first loaded up the Atlas 40, I noticed less fuel economy, no change in throttle response, but strangely enough, more power (tons of black smoke). I loaded up the 2005-2007 version of the Atlas 40 thinking: "I have a 2005 Excursion with a 2005 engine, so I have 2005 programming" No, I absolutely do not....
The strategies I run are VXADB1MZ (what's on the pcm stock, don't care for it) and VXDB1M3 (tuned and much better than VXDB1MZ). These and the other strategies for a 2005 Excursion with a 2005 engine:
EBT1-VXDA1M2
EBT2-VXDA2M9
EBT3-VXDA2M3
VXD0-VXDB1M3
VXD1-VXDB1MZ
.....are based off of 2004 programming and not 2005 programming. I accidentally found this out because for grins, I loaded up the 2004 version of the Atlas 40 and voila! The power, the gasser-like throttle response, and eventually the fuel economy, were there. It is seriously impressive what the Atlas 40 does to either a stock or tuned truck and I couldn't be happier.
(Keep in mind, I NEVER got a code for a mismatched FICM either...)
Prior to this I was running AMZ2AL12 and unless I had a 2005-2007 Super Duty, it wasn't going to run as awesome as it should seeing as it and the PCM spoke the same language, just different dialects. So I'm saving this for the dually I'm dreaming of.
Josh, bottom line, you very possibly could have ended up with a mismatched FICM tune for your strategy, which would explain the loss of fuel economy and black smoke you experienced.
This was also a PSA for my fellow 2005 Excursion with a 2005 engine.

Having an 03, the difference was day and night both in MPG and power, regardless of the power band.

I have a mostly stock 04 F-250 HD edition. When I first bought my truck last November, the Edge Insight CTS2 said I was getting around 13 MPG. I was also running around 165-170 for ECT, with a five to seven degree delta. I installed a Mishimoto 200 degree thermostat. The CTS2 said I was getting around 15 MPG after installing the thermostat. My fuel pressure dipped below 45 lbs on WOT, so I replaced that next. Last month I installed the Atlas 40 tune. With each repair or upgrade, my truck has been more responsive and got better MPG. I noticed a difference after putting the Atlas 40 tune on it. My CTS2 hovers right around 17 MPG. After a long trip of mostly highway driving I hand calculated my MPG at 18.02. Again, a lot of highway driving at 55 or 60, but I'm seen the CTS2 say the MPG was between 18 to 20 on extended hauls on the highway at 65. Your results may vary, but I am extremely please with the Atlas 40 tune on my truck.
