My 05 is stock and i was thinking of getting the atlas 40 tune for pulling power and better mpg, can any here that has got this tell me all the changes you seen afterward getting it?
Got it and had no MPG change. Better tip-in throttle response was the only change. Plus a lighter wallet. IMO it's not worth it on it's own; people will swear up and down they got +2-4mpg, but they likely got it BACK after having FICM problems and getting the tune as part of a repair.
Put an EGT gauge in if you're adding any fuel and towing.
I noticed better throttle response from a start. Noticibly more power too. Also have seen around 1 mpg gain. I sent my FICM in just for the Atlas 40 tune with no repairs. I read somewhere that different strategies will affect the mpg's after the Atlas 40 tune has been installed. Maybe someone will chime in that actually knows and fill us in.. lol.
I had VXCF9H7 paired with ARZ2AL11, then was rolled back to VXCF4H2 paired with an AMZ2AL11 "Atlas 40" FICM tune.
Ed and several people here have told me it's unusual to not see gains, but alas, no gains to report.
I need access to IDS to do an uncompensated contribution test to entirely rule out injector problems, but there are zero signs or data points of any problems; the truck has been spot-on maintained since it was brand new. There's never been a fall off in performance, but no gains either. Ran Archoil 9100 for 10k (2 changes) from 85k to 95k, and other than quieting the engine down some there was no change during/after that either.
Have a read of my post from earlier today.
I for one am very pleased but as I noted I had completed the egr delete prior to the ficm repair & A-40.
My truck is at 115K on the clock and I am very happy.
But if you have other issues like tired injectors or any other things that may be bringing down the performance you should address that first.
But if your truck is healthy from my experience you will not be disappointed!!

I just checked the torque app and my trucks strategy is VXBC9N8 WITH PRZ2AL10. For those Torque App users that don't know, you can find your trucks strategy from the Home page in Torque under Adapter Status then scroll down to Calibration ID. It will be interesting to know others Strategies that are reporting the 2 - 3 mpg gains.
I got the Atlas 40 rolled into FICM rebuild. Mpg was about 8 around town. Now it's about 15. Probably has more to due with FICM repair. No gains on freeway. I have the van and it come detuned stock. Any gain is less on the van. For about $150 I think it's worth getting as Ed tests your FICM.
I would say go for it based on the improvements I got, however as Bryan stated no real improvements for him.
I think a lot of it boils down to the fact a 6.0 is like a fingerprint. There are SO many variables among us as owners that without a lab setting, apples for apples, there are a ton of subjectives. Yes, we all have similarities, for instance if you drive a 6.0 and tell me you are only getting 10 mpg around town I would say that is low, however my driving habits are different than J6P, and maybe J6P is driving a F450 with a utility box and didn't mention that.......etc.
The variations in driving habits are huge, no doubt. Rigs are different, too, both in weight and how they are set up (tire size, injector size/health, turbo set up, filtration cleanliness, tire pressure even, loaded vs unloaded, 4x4 or not, calibrations, etc etc).
All in all, though, we've had a grand total now of ONE person who has asked to go back to their stock tune across the multiple thousands of people who we've done a tune for. That, to me, speaks volumes for the overall happiness factor.

What kinda repair could you have needed to go from 8 to 15 mpg on just the ficm, sounds interesting.
This is our most popular tune and comes with all the benefits of the Eco tune, but with more oomph available to you just generally, even with an ECM programmer. If you are not set up to monitor your exhaust gas temperatures and run stock exhaust, this could also be an option if you tow less than 8000#. Gains of up to 40 horse power to the rear wheels can be seen.
If you tow over 8,000 pounds, though, this option is only recommended if you have a way to measure your exhaust gas temperatures or if you have upgraded exhaust as the power added results in higher exhaust gas temperatures. The higher EGT's are largely caused as a result of a decreased need to downshift to maintain speed up a grade, thereby loading up the engine without an increase in airflow. Note that there is up to about a 75% overlap in the power adding capability of this tune with an ECM programmer, meaning that the power benefit will run close to 'just' 10 additional horsepower. Will you still 'feel' the difference, though? You bet!

I worked with Ed & Jason there. They have a great option IMO. They sent me a FICM tuner so I could try all 4 of the FICM tunes first. That way I could test them out see which one fits me & my setup the best. So for the shipping costs (and a deposit which I received back when the tuner was returned) I got to try all 4 out before I bought. Awesome -
There are more details on my experience in this thread:

like everyone says-too many variables. The FICM was toast. My thermostat was stuck so I replaced it. It was running off 1 battery. it was 8mpg while driving it cold. The Atlas 40 did not improve mpg. Rebuilding the FICM helped.

I wonder if something is either different in an '04, or if they changed something in Torque? I haven't looked for awhile but there wasn't even an entry for FICM strategy and the PCM calibration only came back as VXC (or maybe it was VCX). Anyway thanks for posting this -- I'll go check it out!
