I have had my Gryphon for about 5 months with the gotts mod. Two days ago I ordered a CAI. I got it today, installed it after returning my truck to stock. I have placed an order today to re-tune the custom calibrations I had set my truck back to stock since my gryphon is not set up for a CAI. Well I after doing my first test run with the CAI, check engine light came on and I got two lean codes. (171,174) I am seriously worried now. Do I not need to drive my truck until my new custom tunes arrive for the CAI and put my stock intake back on for now? I am just scared to drive my truck....




2004 (new body style) F150 5.4L 3v? aFe Stage 2 fully enclosed CAI.


THanks.

 

put the stock intake back on until you get the tune. Those engines are lean from the factory adding a CAI makes it dangerously lean.

 

What he said. Wait for those custom tunes and you will be pleased.

 

You didn't check the FAQs on PHP's website or forum.......you also didn't read the instruction manual that came with the programmer......catch up on some must needed reading and I'll get back to you......

Take care ........

 

Man I returned the truck to stock before I even installed the CAI. So it shouldn't of made a difference about the programmer. It's just model year of truck from what I read now.

 

Why did you waste your money on an intake? It's not going to run any better than with the Gotts mod.

 

With regards to “Chips” and “Tuners”, years ago it was the best that most could do to enhance the ignition timing, fuel curve, transmission shift points, etc. It was (and still is) very important that a person verifies that the “Tuner” is ASE certified in both ECM and Transmission programming and IMHO be have current certification by the OEM whose vehicle you want to modify. There are plenty of persons who advertise their programs to be the best and even offer custom tunes, but in all reality, very few actually have credentials in these areas- but that’s not to say that some of these “geniuses” haven’t really caused damage to a few vehicles- just jump over to flatratetech.com and read just some of the comments from the MSE techs!. Perhaps what is equally important is the parameters that can be adjusted are set by the OEM vehicle software…so there is really no “magic” in what they are doing anyway. Now about this new marketing hype that if you have a CAI you need a custom program………….hogwash!!!!!! The OEM software system is designed to adjust the fuel mixture up to 10%.......that’s more than enough to handle fuel mixture adjustments up to 7,000 foot elevation change! (for high elevations 8,000+ there are oem software programs for those specific applications) The 5.4 V8 for example if close to stock can only suck in a maximum of 480 cfm and a flat panel filter will flow 500 cfm, there is simply no way any CAI on a relatively stock engine can increase the air flow enough to exceed the ECM’s ability to adjust and maintain the correct fuel mixture. The only reason for the “custom” program to support the CAI is because the design is poor resulting in false readings from the air intake sensors, etc….period! If you look at the dyno charts from many of these supposed HP/TQ increases, they are typically around 5%-7% at peak rpm ranges…….guess what, 5% is a standard deviation even amoungst mfg dynos and the most important item is……these “expert tuners” (at least most) do not have or choose not to test their results (in comparison to the oem intakes) during actual vehicle motion (or simulation- such as a wind tunnel) as the oems do. What many view as an issue (is the plastic intake tube with its noise canceling design) actually increases air pressure. It is the same hydraulic concept used by fire fighters creating water supply where psi is low. By having the air cross the path at a 90 degree angle, the pressure is increased proportionally. Fire fighters use what is called a “4-way valve” or “Blake Valve” at the hydrant where the water is cycled through the fire engine (pump) and sent back into the valve crossing the water flow at a 90 degree angle. In this case it also acts as a sound canceling device! At low speeds, this can reduce the flow a tad (which is what most “feel”), but in terms of peak hp/tq, a good high flow filter is all that is needed.

Recently, Testand Corporation conducted an ISO standards test on automotive air filters which can be viewed at this link: http://www.dieselbombers.com/chevrol...r-testing.html. All I can say is this explains in detail the reason for

“Now that I am not doing the tests and my objectivity is not necessary, let me explain my motivation. The reason I started this crusade was that I was seeing people spend a lot of money on aftermarket filters based on the word of a salesperson or based on the misleading, incomplete or outright deceiving information printed on boxes and in sales literature. Gentlemen and Ladies, Marketing and the lure of profit is VERY POWERFUL! It is amazing how many people believe that better airflow = more power! Unless you have modifications out the wazoo, a more porous filter will just dirty your oil! Some will say " I have used aftermarket brand X for XXX # years with no problems. The PROBLEM is you spent a chunk of ching on a product that not only DID NOT increase your horsepower, but also let in a lot of dirt while doing it! Now how much is a lot? ANY MORE THAN NECESSARY is TOO MUCH!

Others are persuaded by the claims of aftermarket manufacturers that their filters filter dirt "better than any other filter on the market." Sounds very enticing. To small timers like you and me, spending $1500 to test a filter sounds like a lot. But if you were a filter manufacturer and you believed your filter could filter dirt better than any other media on the market, wouldn't you want to prove it? Guess what. Test your filter vs. the OE paper. It will cost you $3000 and for that price you will have the data that you can use in your advertisements. Your investment will be returned a thousand fold! EASIER than shooting fish in a barrel! So why don't these manufacturers do this? Hmmm? Probably not because they would feel guilty about taking more market share.



Now I am not saying that ALL aftermarket filters are useless. A paper filter does not do well if directly wetted or muddy. It may collapse. This is why many off-road filters are foam. It is a compromise between filtering efficiency and protection from a collapsed filter. Now how many of our trucks collapse their filters from mud and water? However, if a filter is using "better airflow" as their marketing tool, remember this....Does it flow better? At very high airflow volumes, probably. BUT, Our trucks CAN'T flow that much air unless super-modified, so what is the point? The stock filter will flow MORE THAN ENOUGH AIR to give you ALL THE HORSEPOWER the engine has to give. And this remains true until the filter is dirty enough to trip the air filter life indicator. At that point performance will decline somewhat. Replace the filter and get on with it.


IMHO, if you live near any major city there are excellent tuning specialists with dynos who for the same price (if not less) will tune your vehicle taking into consideration your specific needs including environmental conditions, for your specific vehicle. IMHO, the best bang for the buck!

 

i noticed a difference from that run i did......and i had the money for one.

 

My JLT made a difference over my Gotts+K&N....

I think your enclosed intake will be better too

 

well I say blow the money you earn on what you want buddy. I think thats the cool part of earning your own money, you can buy what you want!

Hell if it looks good, and you like it buy what you want! enjoy brother

I would pull it off if it aint to hard and run stock till codes come in!

 

Funny thing to me, how is it no different when it needs different tunes? Oh wait that rights....it's running lean because of too much air intake. So it is getting more air flow which means there's a difference!!!!!!!!

 

Guess I missed something here..you said you had the Gryphon on with the Gotts mod for 5 months. With the addition of the K&N (waste of $) you shouldn't need new tunes as it was already tuned for the extra airflow and by going back to stock the calibration changed on you. Just re-install the tune you had and you should be good to go. Tell me what I missed here.

 

Typically, the CAIs reposition the MAF to the point it cannot measure all the airflow. This can cause a problem.

 

OOPS..forgot about that little piece of info.....Thanks :o

 

He didn't get a K&N, he got an AFE Stage 2.
It evidently flows more air than the Gotts did, which is why he needs new tunes.
