It should be, with a previous stock setup after an Atlas 40; 365 HP and 700 ft.lbs of torque

 

My rig has 230,000 miles on it, rarely towed with. New injectors, new HFCM, blue spring, new ficm, dummy plugs stand pipes. My ficm was definitely killed, my truck didn't dun at all wit the last one. Anyways I think with its current condition it think the atlas 40 would be a good option, seem like a good idea?

 

I think your dreaming with atlas 40 making 700 Ft.lbs of torque....
The major difference with atlas 4o is a lot better throttle response.. Also if you go to atlas 80, bye bye to towing in the future...

 

I got that from the dyno tests that have been performed. Not on my truck. But what I can find.

I don't think that the Atlas 40 adding an additional 130 ftlb of torque is dreaming.

I didn't say the Atlas 40 was making 700 ftlb of torque. I was stating combine torque.

 

You can buy the tuner itself and you can run whatever tune you want to. I'm sure Ed has the complete tuner for sale as well.
I also agree with Silverbullet6.0 that you are much safer to go with a FICM tune over reflashing the ECM and running a engine tune.

I have the tuner and I like the ability to change it up when I want to. I really like the Atlas80 but it does make more heat especially if towing or climbing up the mountains.
The Atlas40 is best all around I'd say and what I usually have loaded.

That said installing a 4" exhaust will compliment the Atlas40 for sure. Dyno results are 375HP with Atlas40 and 4" straight exhaust per PHP themselves.
I paid $450.00 many moons ago for mine, not sure today. Buy it through Ed because it will be same price or cheaper than it would be if you went straight through PHP.
Reason I say this is because of the customer service that you will get through Ed.

PHP is hard as HELL to get ANY RESPONSE OF ANY KIND from and Ed will jump through hoops to answer any and every question you could ever have. Plus he has vendor power and he will make sure that you are taken care of if you had any problems.


As far as keeping a mellow exhaust note, there are many straight through 4" mufflers out there that will keep the 6.0 crackle to a manageable level. As strange as this may sound the biggest difference you can make is: knock out the cat honeycomb and weld 4" pipe on both ends. Then mount it back in your exhaust system at the OEM location. That open area of the cat knocks down the resonance as well as the harsh crackle at wot.
Strange how it works but trust me it does. If it's still to noisy for you them get a muffler on it too. I have a Corsa on my truck and it sounds like a big block gasser almost at wot. Has a deep tone to it instead of the growl.......

Hope this helps and call Ed.

 

Did you get the batteries load tested and the alternator bench tested?

Here's the dyno graph results:




Not every truck is the same, but this is what most of have to go on for info.

 

Thanks for the replies! I just got off the phone with ed and hes leaning me towards the 40 being that I dont have exhaust. He said we can do a egt gauge if i want the 80 horse, but we just have to keep those in check. What do you guys think between the 40 and 80? By that graph it appears that the throttle response should be about the same from a stop but down the line is where the higher horse comes in. Is that accurate?

 

You already know my vote, LOL

 

I'm so torn... I don't tow more than a boat, and am fine getting a egt gauge and possible cat back exhaust. So I'm leaning towards the 80 horse. But with my current setup the 40 is better. Would you say the 40 is night and day or just more of a wakeup?

 

Now your getting into opinion based questions, so with that you should be leary, as alot of people have different opinions, and what feels "more or less" to them.

For me it was night and day. But that is because I had the most current flash from Furd on my FICM, which equaled bad mpg's, and lack of power.

I also asked the same question before getting my FICM tune, cause I was worried that the Atlas 40 wouldn't be "enough" for me. Everybody that I talk to said that I would be very happy with the Atlas 40tune. You should Gooogle some reviews and read others responses to the Atlas 40 tune.

 

Very true, I've been reading up all day. Some say its huge some not so much. Have your heard of there being any risk to the head gasket? I haven't but just curious

 

Plain and simple if you want a wake up and quicker turbo spool go with the atlas 40.if you want a lot of horsepower go with a tuner.heck some of us do both.

 

I was concerned about the exact same question, as this was the reason I almost did not go with a tune, because I didn't want to have the reliability and integrity of the engine and transmission compromised.

You should not have head gasket issues with the Atlas 40. If you do have issues after the tune, usually its because the issue was already there. So if your HG's are good, then there should be no worries.

 

Yeah, its plain and simple now to me too, only cause I see how the Atlas 40 is on the 6oh. But I know that the twisting and turning of the mind in this is a battle, cause some of us are so "worried" about screwing up a good truck.

I know I was.

 

Atlas 40 and 4" straight pipe, woke my 6.0 up straight away. If I pounce on it she will get sideways like nobodies business
12 to 14 mpg city and 20 or just over highway.
Mine has the signature early build turbo whistle, muted just slightly with a really small muffler.
For some, Atlast 40 is night and day, for others........meh.

Depends if you have a crappy flash.

Unless that boat you are towing is a 30' plus twin screw Baja you are prlly overkill with an Atlas 80. Just because it says Atlas 80 does not mean you are getting 80, likewise with any other tune. Other factors enter into the equation.
