Could someone tell me the difference between the 3'' and 3.5'' tubes? And if the 3.5'' tube is ok to run with edge programming? Moss motors has the airforce one for 15% off and I was gonna buy there but wanted to make sure it was the best (ie) the 3.5'' tube. Thanks for the help.

 

The Edge can't correct for the extra air that the 3.5 inch can flow. If you want the 3.5 you will have to get custom tuning to prevent running lean and have a CEL on all the time.

 

doesnt the edge correct CELs tho?

 

The EDGE can clear codes which will turn off the CEL but unless you correct the underlying cause the CEL will come right back on. The EDGE tuning does not address the extra air which will run the engine lean.

 

Ok that kinda sux. So how do I know if the one Im getting is the 3'' or the 3.5'' since I guess Ill be needing the 3"?

 

On the 04 the PCM is especially sensitive to replacement intakes. Even with the 3 inch you may still get a CEL and lean codes. This is because the limits in the PCM are too tight in the 04. I had a 3 inch on my 04 and it kept tripping the CEL and I wound up eventually getting rid of it due to that and the extra noise it made while towing. Custom tuning can fix the lean condition.

 

Yeah, the EDGE can clear CEL lights, but it cannot correct the lean condition that results from the 3.25" AF1. Just using the EDGE to clear the CEL everytime it comes on is a sure-fire way to kill your motor.

 

I havent messed around with the edge custom tuning too much is it capable of adjusting the fuel to correct the lean condition for the 3"? And lastly how do I know/specify which tube size I want? Thanks for the help.

 

No. The only fuel adjustment is the ability to alter the amount of fuel at WOT. Sorry.

 

I got the 3" on my 06. No problems but I don't have a tuner. GOt mine from Troyer. In my experience Moss is more expensive on almost every product. Check to see if the forum group by is still going on with Troyer.

 

Ford changed the PCM tuning after 04 to make it less sensitive to air intake changes. So you should be OK with the stock tune.

 

....on a 3" AF1. Anything larger then that and your truck will run lean, plain and simple. It doesn't matter if it's 3.25 or 3.5, it'll be lean. The only difference is the 3.5 will be leaner.

If you want to use the 3.25 or 3.5 then you need to be running custom tuning for the larger intakes. I'm not 100% sure but I think TP is still in the research faze of the 3.5 and it isn't in full production just yet.

kd4crs,
What you're saying is kind of contradictive. From what you're saying in the first couple posts if he get's a CEL his engine will eventually blow from running lean, but in your last post you're saying that the only reason he'd get a CEL is because the paramaters are tighter on the '04 models and all is good.
It's still the same amount of air going in if he puts the same intake on an '04 truck as on an '05 or 06. The trucks are tuned the same(ish), just the paramater that tells the CEL when to turn on has been "expanded" (can't think of a better word right now).
The edge probably changes that paramater anyways. He may not be able to adjust the air/fuel but it may be already programmed in. I remember Bill (Edge engeneer) said it would work better with a CAI so they must have done something.

 

Let me clear this up. According to Mike Troyer, you can run the 3 inch without custom tuning on the 04-07 F150. You can't run the 3.5 inch on the 04-07 F150 without custom tuning. It was my personal experience (as well as many others) that I could not run the 3 inch AF1 on my 04 F150 without getting a CEL. Troyer dyno'ed some 04 F150s and the datalogging showed they did not actually run dangerously lean even though they tripped a CEL. In the 04 tuning Ford set the lean limits too tight. Now, taking the previous information into account, some 04+ F150s have been found to run lean with just the stock intake and filter. Bottom line is that the 5.4L3v engine/PCM combination is petty finicky about air intake changes.

 

I special ordered my 3.5 from Mike Troyer and he customized my three tunes for it ( for the XCAL 2 ). I am just waiting on it to arrive to replace my airraid intake.
Should be here in the next week or two.
Its going on my '05 5.4
