Agreed, I wonder if Mr. Troyer has that fancy machine of his fired up as we speak...

But the "intake passed with flying colors" ....... so why all of a sudden design changes? Is there something really wrong with the old design besides the CEL, rough starts, idle issues, lean conditions, and horriable drown noise?
What gives... could there be more issues here than we know about!?

Why would AF1 sneak this new model out?

I spent a lot of money on this intake trusting the word of a Troyer's review.
Sure it dumps out more HP, but at what price to your engine? Kinda makes one wonder how credible these sources are.

 

I called AirForce One performance and discussed these issues with Everett yesterday. They redesigned the tube to address the CELs that some people are having. He said the new tube has not been dynoed yet but that they don't anticipate a significant difference in performance compared to the original tube. Mike Troyer has already proven that the CELs and lean codes are due to the PCMs limits being set too tight from the factory and that the trucks are not actually running lean. I didn't ask about the noise level being any different. Nobody is "sneaking" anything out. The manufacturer has made a design change to address customer concerns. There is nothing sinister going on. Everyone should be glad that AirForce One and Troyer cares enough about customer service to do the right thing by their customers. Lets give credit where credit is due, OK? For any other questions, I suggest calling AirForce One directly, like I did, they have a toll free number. They will be happy to answer any questions you have.

 

Why does the noise level even come into question? Mine is totally quiet until I jump on it, then it screams.

 

The new AF1 style (2nd generation) should not have been released by AF1 until it was properly dyno'ed. It will be interesting to see what the new statistics are that Mike Troyer will hopefully turn out by testing the new AF1 tube. I wouldn't trust any numbers sent out from AF1 as it wasn't good business to release a new version without providing a dyno of new outputs.

Hopefully Mike's testing, if he does, and hopefully it won't take too long.

 

Mine is louder than my exhaust is no matter were I put the filter on the end of the tube. It plays an awful note in the cab at any speed. FYI

 

The AF1 claims most HP and torque gains but at what cost? I was half way to ordering one until I read this and another thread. Do they still have the most HP gains and if so by how much? Is the new difference worth the cost? I can't imagine that little of change could affect it all that much, but then again, if I knew the physics I'd build one myself.
If it wasn't actually running lean and it was just the PCMs limits being set to tight from factory as according to Mike then why did they even bother reengineering it? Just print out a one line warning message with it that states that.
If it fixes the CELs and any other issues the origional AF1 had, then great but I agree with most people here. You can't mass produce and distribute a product you haven't tested yet.

 

Tical84,
I agree that the gains are relatively small relative to the cost, in terms of horsepower gained. Where it seems to make a difference is in terms of torque. Mind you, it my seats of the pants feel, I have no research to back it up. But small things add up, as with a tuner and intake, the truck feels lighter and more "torqey"...better acceloration and maybe better gas milage if I can keep my foot out of it. Is it worth the cost...thats really subjective. Also in the manual with the intake it does have the CEL issue clearly stated as a problem on some of the vehicles, I feel that if AF1 hadn't of tried to address the problem then many would have been scared off to buy one. So i applaude them making the change. Just my two cents worth.

Don't get me wrong, I'm glad they made the change too, especially before I buy mine. I'm just saying I think it would have been wiser to test the product first. I'm sure if you went to the dealership to buy a truck because you wanted to haul a 4000Kg boat and asked them how much the truck could haul, if they said "I don't know, never been tested" would you feel safe towing that boat as apposed to "It can haul up to 4250Kg but a warning light in the cab will come on"? Maybe an exaggerated comparison, but you see my point.

 

Yea, I agree this second version should have been tested before it was released. Although I don't know to what extent the 2nd version was tested. I have the first version and I love it. It's the best performance bolt I have ever purchased and that includes the stuff I bought for my Vettes. The "seat of the pants" feel with horsepower and torque is very noticeable. The "noise" for me starts when I put my foot in it only. Along with the noise, is a little harmonic vibration, but not to the extent it is bothersome. I did not have any error codes and my FX4 is basically stock.

 

what I don't understand is they spend over a year and a half doing r&d on the old tube. I would have thought they had the issues solved. then they throw together this new design with how much R&D, none that I have heard of. why did it take so long for the first version to come out and so quick for the second.

 

oh yah and the new version is noisy too. I didn't realize they were so noisy. its at least twice as lowd as my exhaust. especially when I step on it hard. you would think I was playing a trombone when I lay into the gas. I am going to see if I can do something to reduce the vibration which hopefully will reduce the noise.

 

Jasonkola,
I had the same "blowing in a bottle noise" until (as others have said to do), pulled the aircleaner back the the end of the tube, this noise then went away and its quite unless I goose her.

Am I reading correctly that there is a major sound difference on the new model? I think I'm still wanting to get the AF1 but I was also having more of a sleeper. I realize that at WOT all intakes/exhaust get pretty loud, but that I'm ok with. I just don't want to blow everyones ears off when I'm cruzing downtown with the intake or exhaust...that's what my two 10"s are for

 

I got it as close to the end as I can get it. I spent an hour yesterday trying to get it closer to the end but it kept slipping off the end of the tube when I tightened it down. I saw one guy on her flared the end of the tube out a little to keep it from slipping off but I don't have the right tools to do that. so I did get my dremmel and roughed up the end of the tube to get it to stay on. I think I am going to go aout again and try cleaning any oil that might be on the rubber or boot and tube off and see if I can't get it more on the end. also I am not going to tighten it so much I was trying to get it super tight.
