What are you numbers looking like for MPG?
How is the truck responding?
Are you getting any smoke?
If you have an EGT probe how are the numbers with that?

Atlas 40 with SRL Extreme here. I'm sure you've seen my mods by now Sean. Average MPG with 50% in town and 50% highway is usually around 14.5 MPG. Average when I drive mostly highway is about 18.5. Pure highway I've pulled 22.5. I'm sure these numbers would be better yet without a lift and the big M/T's. I also definitely do not drive the truck like an old man. As far as smoke goes I get one small black puff on startup and only get smoke at low end speed with at least 50% throttle. If I put it to the floor at low end speed it'll leave a decent cloud until the turbo clears it up. EGT is generally about 700 cruising down the highway, highest I've seen it with a WOT pull was about 1400.

 

are you studded OP?

 

Pretty much the same as Auto tech, SRL+ tune. Smokes a bit until turbo catches up, but my turbo is gettin wore out too. My mileage has been around 15 mpg. I do drive like an idiot, though. I put the 8k tow tune on now as it is a little harder to be obnoxious with that tune.

 

Had to stop running SRL and Atlas 40.

Mine smoked like an old coal locomotive trying desperately to pull a grade.

But I understand all '07's do that... Still doesn't make a win when living in a city full of bicyclists with political power.... :-(

Atlas 40 with 8k tow. Getting about 17.2-17.5 avg. Mix of miles is probably close to 50/50 highway & city. No smoke. F350 CC dually longbed 2WD with 4.10 gears

 

A stud set is in the plans but not yet.

RANT WARNING

The first spring I owned this truck I did give some guy on a bike a cloud
to inhale. The bozo forced me out into on coming traffic with a stupid
move on his part. I munched the peddle to the floor and for a good
size PUFF. I have found it hard to get any smoke out in most cases.
That time I was at about 30 going up a slight hill and was at 55
before I knew it.

Lesson is if your on a bike in traffic don't be stupid with a 8,000 Lb
truck coming up on you. The thing is it was his stupid move and IF
I had hit him guess who would get the blame.

END RANT

For the most part I also find that Matt's 8k tow tune keeps my
food out of the fuel tank and still gives me a lot of PEP.

I'm running the Atlas-40 and have run both the 8k Tow and SRL.

For MPG's I do about 75% highway 25% town driving and am pretty solid at a hair just over a calculated 16 mpg and that's for both the 8K Tow and SRL.

Regarding the smoke I do get a little puff on take off if I'm somewhat easy on it and get bit more if I take off hard. But while cruising or idling it's pretty much smoke free.

And then for EGT's: Stock @ 80 mph on a flat highway I would run about 700*-775*. On the SRL tune @ 80 mph and flat road I am getting 575*-650*. On the 8K Tow with same speed I'm seeing about 600*-675*.

 

So did you guys feel the Atlas 40 added something to the tunes or not really? Mpg increase? I have SRL++ and get 14 mpg strictly town driving. Highway trips are rare but definitely over 16mpg. I would get the Atlas if I thought it would do anything for me...

 

Atlas 40 plus the canned SCT 120Hp performance didn't smoke at all for me Is that a problem with the Gearhead tunes in general?

 

When I talked to them I told him I did not want any smoke and that
may be where he was coming from. Small puff every now and then
would not be a problem. It's the black cloud trailing behind me I don't want.

Sean

 

On mine, yes. Even the VXCF4 STOCK program smokes visibly with the Atlas 40.

The 60-HP canned Street tune smokes when I get into it, but it's not the boiling cloud of coal that the SRL was...

They'll clean up considerably once it's under full boost (and usually 100+ MPH by that point) but on the takeoff, you don't want to be in the same county.

It's been almost two years on this thread and by now plenty of other users have these tunes and the Atlas 40.

Please post up your experience with Gearhead tunes and the Atlas 40

 

I've ran the 8k tow and the SRL+, both smokes a little when I get on it but nothing too bad. I didn't notice a fuel increase with either, probably for good reason!

I moved it back to stock until I can get it studded. Self control isn't too hard until you meet that ID10T on the highway... Temper tends to take control of self... . Anyways better safe than sorry....

 

been running them for a year. SRL as a daily driver and only smokes if i get on it at from a stop. Not huge but small cloud. Normal driving i dont see any.
