I know that a CAI isn't necessarily a Chip, Tuner or Progammer but this part of the forums seem to be the only place that likes the AF1! In the 2004 & UP threads, all I read about is the Volant and K&N

Anyways, superb product. Installation was easy and the road tests fun. The initial "sucking" of air noise it makes when you TOUCH the gas is great. Kind of like when you inhale real quick.

At reagular driving (no gunning) sounds pretty much like stock but a tad meaner. HOWEVER, at WOT the AF1 growls like it's hungry for air. OMFG, it is almost embarrasing getting on it because it sounds like you are one of "those guys" with jacked up trucks, Calvin pissing on whatever stickers, or even the dreaded "Sit down, shut up, hang on" stickers.

Sorry, back to the point. I couldn't be any happier with this purchase. The instant mileage display on my Scanguage is also showing improvement! Granted, I had it installed for one day now but even the current day mileage display on the display reached to almost 17 with all in-town driving.

I can only deduce that the XCal II WITH the AF1 has to be a requisite for these trucks.

Oh yeah, no CELs showing, just made sure everything was nice and tight.

Yet again, many thanks for Troyer Performance for these products and Crystal who always seems to be there when I need her most

Now time to save up for a SISO Magnaflow.

 

 

Hi beowolf,

Thanks for your post, I'm glad you are enjoying the AF1.

At some point if you get a chance, I'd love to see some data on it, particularly the A/F's, just to make sure everything is staying in line. It sounds fine, but data really tells the tale, so if you happen to get that done, do let us know.

Thanks again for your post & have fun!

 

Thanks Mike,

I agree that the A/F data is the best way to make sure to avoid the truck running lean, but from my understanding with Crystal, the 4.6L doesn't need to be dyno'd. Or do you still recommend me heading to the dyno?

Thanks in advance.

 

This is something that we have talked about a lot here. Being a tuner I naturally prefer to see A/F's on any vehicle with a non-factory intake kit. So personally, I always like to see the truck be dyno'd, even more so in the new body style trucks.

Now in the 1997-2003 trucks, with a good intake kit, we do see them go a bit lean - not lean enough to hurt the engine, but lean enough where I like to make an adjustment in some cases. Once we get into the 2004 F-150 with a 5.4 3V, then a lot of intake kits cause lean conditions that actually require getting those A/F's so we can correct them. Now in *those* trucks, if they have the 3.0" or the 3.25" AF1, or the Volant or Airaid kits, we have developed transfer functions that work very well and generally delivery very safe A/F's.

In the 2004 4.6 F-150's, usually they follow the same pattern as the 1997-2003's - they will lean out a little bit, so yes, I'd like to see A/F's, but they generally don't lean out enough to actually hurt the motor. However, in the 4.6 F-150 once we hit the 2005 model year, we do see that a lot of intake kits cause lean conditions that have to be corrected - for example, even in bone-stock trim, a 2005 BUF3-code F-150 will run about 15.0:1 right off the showroom floor. But slap an AF1 or an Airaid on an HEV0-code 4.6 F-150 from the same model year, and they seem to stay pretty close - go figure!

So what's the answer? Basically like I said originally - If you get a chance, do the datalogging as we describe in our docs, and let me take a look at that data. Our staff & I just talked about this at length as well again today, as it is a bit of a judgment call depending on the individual vehicle, model year, engine, & what intake kit, as it's tough sometimes for her to remember everything ands keep up with all the changes that I make as time goes by and we get more data and I change how I feel about certain things, too.

Regarding this section liking the AF1 & the other section not - well, unfortunately down there along with some decent info there are also some histrionics & some non-factual info in some cases - you will find some who claim it took them 3 hours to install the AF1 intake kit, where in our September 2005 Dyno Day we did a demonstration of how it can be easily installed in just 12 minutes by our guys - and that anyone with brain who has never done it before can do it in 30.

In fact, at our last dyno day event here, we showed people what intake kits did exactly what among the numerous vehicles that came - for example, how the Volant kit hurt power in these trucks compared to the AF1 especially in the 5.4 3V's, it caused horsepower and torque to nosedive quickly as rpms rose. The proof is in the actual performance, and not once on any vehicle we've tested has any other intake kit out-performed the Air Force One on these vehicles.

Now all of that having being said, we truly hope everyone is happy with whatever they get - to each their own. We don't care what it says on the box, we care about the actual results from the product inside - which is why so many people come to us for our experience with this platform, and why our customer's trucks out-perform others with the same basic level of modifications.

Anyway, I'm just rambling, I don't mean to sound like a sales pitch - glad you like your AF1!

 

Thanks for the response, Mike. Very helpful. I will head to dyno ASAP for me do so (money talks). I'd like to see the performance jumps too. Again, thanks for the informative post.

 

You're very welcome, as always!
