Initial dyno results for the 2009!
I absolutely died laughing when I read his caption for that picture...
That's funny, right there! I don't care who you are! 
So what do you think, Jim? Did I capture the essence of the droning sound, or did I somehow not hit it squarely? It's such a tough thing to describe.

Okay... one more correction on the Barometric Pressure situation.
After poking around a bit, I did find that the "absolute" barometric pressure 26.65 was not too far out of line. Here is a cool calculator I found that will provide the absolute barometric pressure for a given altitude and temperature.
http://www.digitaldutch.com/atmoscalc/
The only issue I have with the calculator is that the barometric pressure reading from the dyno would indicate that we were closer to 3500 feet, but I'm not taking into account any variance for local atmospheric conditions. I do know that the day I was dynoing the truck was right after the nasty snowfall condition. The sky was clear and I would assume the barometric pressure was rising at that point, even if only a little bit. So I will stand by the original pressure values.
I went back and look at several other dyno plots just for reference and did find that 26.6 was the average pressure for our location... some days were a little higher, some days were a little lower.
Later.

No worries on the AFR thing. It happens to the best of us!

This was done through actual tuning of the ECM. We took the stock calibration and applied much of the same tuning we would use on the earlier F-150. We are finishing up the firmware and will have the calibrations available on the Evolution and Gryphon platforms in the next couple weeks.
As for the separate ECM/TCM, it's not a big deal at all. The 6.0L diesel has had the same setup for years and we already know how to handle that. In fact, even the 6.4L and later Expeditions use the 2 module setup. I'm not all that familiar with the Dodge setup, but from what I understand this certainly is much easier to deal with.

Now, one comment on the CAI/AFR thing... The reason a CAI will often cause a lean condition is because the shape and/or diameter of the metering or "sample" area of the intake tube is usually quite different from stock. This change will have a significant effect on the way the Mass Airflow (MAF) Sensor calculates the airflow into the engine. The larger the intake tube, the lower the air velocity through the tube, and consequently through the sampling port of the MAF. This results in a lower output from the MAF which the computer interprets as less air mass entering the engine and in turn cause the computer to inject less fuel. You can guess the rest from here. Since removing the snorkel does not change the sampling area of the intake tube, there is no adverse effect on final AFR.
Enjoy.

Bill do you think that it would hurt running the intake with the tube removed from the airbox? I have done this before and gained even more power but was scared about the leaning issue. I don't go offroad and the intake air temperature didn't get very high either. So i'm not really worried about getting water in the intake.
I've run it both ways... With the tube completely removed (like in your picture) and with a piece of PVC tubing to route the airflow back into the fender. The difference in performance was minimal. Just think back to the '70s and '80s when ALL air filter systems had an open orifice under the hood.

This setup never hurt anything and neither will yours.
As a side note, I don't see any reason to cut off the noise filters or "mufflers" as you called them, unless you are looking to clean up the visual aspect of the intake. Keep in mind though that they do serve the purpose of eliminating certain soundwave frequencies relating to dreaded drone.

Just do like I did. I just removed the snorkel and got a jig saw and chopped off the muffler's on the intake. In this pic the muffler's are still on the intake tube but they are gone now though. I noticed a nice power increase with this setup and a k&n drop in filter. My intake air temperature usually run's about the same as the outside temperature unless I get stuck in traffic then it will get hotter than the outside temp.


I have an edge programmer installed in my truck.

Thanks for the info Bill! I cut the noise filter's off to clean up the underhood appearance. So far I haven't noticed any droning.

Take care.
That is what I was guessing, do u change the tunes or do u mostly use it for guages and how doesit work for u I would like to get one just for the extra guages but couldn't find anybody that had one do the guages work pretty good and can u get tranny temp on the edge???

Nah... babies are cheap.
It's the diapers, formula, clothes, toys, doctor visits, assorted medicines, daycare, and baby sitters that are expensive. 
Figure the average delivery costs $8000.00 without insurance (including prenatal) or if you have insurance then it's around $2500.00. Daycare alone for the first year could run a minimum of $3000.00. Add another $1000.00 for diapers and another $1000.00 for formula for the first year. $2000.00 on clothes (those stupid little outfits are EXPENSIVE!) and another $1000.00 for doctors visits.
Assuming no major illness, you've got a minimum of $8000.00... Just for the FIRST YEAR! By the time they're 4, you'll have spent over $27,500.00 (decreasing diaper, formula, doctor and clothing expenses as the child grows) and again that's not accounting for any medical problems.
The funny thing is all that pales in comparison to the cost of education. If you plan to send your kid to college (and paying for it) then you may as well plan on paying about as much as you paid for your house.
Makes you wonder why anyone has kids...
It must be love, because nothing else makes sense!
