I am a new member to this awsome site and maybe so of you experienced people can give me some insite. I have a 2000 f-150 4x4 with a 5.4L and want to add a chip and k&n air filter, what type of chip should I use and how much will this help? The air filter, will this help performance or what do you recommend.

Thanks,

For the air filter, you have a few routes to go.

Currently I still have a K&N FIPK on my 5.4. It works great.
I am doing work on checking intake temps on open vs closed airbox FIPKs, to see if the cool air really is a big difference.

The K&N while moving only has about a 5* delta from outside air temps, and the MAFS flow Rate is really good.
Once I get the WMS V Tube and intsall the JLP airbox, I can get closed airbox temps to compare it to ( stil be about 2 to 3 weeks before the results on the second are done, the WMS V Tube seems to be taking forever to get here ).

I would suggest though, if you are changing the air filter, to go with the FIPK, rather then the drop in. The FIPK does allow the engine to break easier, when coupled with a good Cat back xhst system.
I put the FIPK on first ( the night it came home ), and then the cat back the first weekend.
So the starting point would be IMHO FIPK and Cat back xhst system ( I have the Gibson Super Truck ).

Once you do this, drive for awhile then think about the chip.
You would want to do anything else mod wise to the truck before the chip to save on reburning the chip after the fact.

Another suggestion while doing the FIPK, replace the MAFS. I put a GMS MAFS on this spring, and it seemed to make a lot of difference to the truck. I need less pedal to get the same going movement out of the truck now that the stock ford MAFS is out of there.
The MAFS is almost 400.00 so it is not a cheap upgrade, but in my mind worth the investment. Add in FIPK almost 200.00, that is 600.00 on the intake alone. Then add in a Cat back system, and you are almost 900.00 in mods right there, and you have not gotten to the chip yet.

If you have a 4R100 trans, look into the Factory_Tech valve line mod for peping up the trans.

I do not have a chip yet, and can see several ways of getting to the drivability out of the truck without it. That is me right now, I might go the chip route later, once again when the other mods are done so I only have 1 burn cycle to pay for.

Just food for thought, albeit too much
See what comes your way I am sure the next post will tell you to put a SuperChip in it right now

 

www.jdmengineeringinc.com They might have some better products at a lower price. I personelly feel that there is a few better products than GMS products. one of the cheaper mods you can do yourself is buy a K&N filter slice open your air box and remove your silencer. at www.Fordf150.com they show you how to do this. cost about $40 Some other Mods out there are of course electric fans and underdrive pulleys. both adding about 10-15 HP Needless to say you can mod out your truck really easy with just bolt on items. What you need to figure out is how much $ you have between mods. If you are able to buy all of your mods other than the chip in a small amount of time do that but if it takes you a year to get a mod or not interested in buying tons of mods I would go with a chip.

 

Thanks for the info I think i am going to buy the k&n or the airraid FIPK system and the gibson side swept cat exhst, any more info would be greatly appreciated from any one else.

Thanks,

Blue Dog

 

Thats right modify it!!!
Ford made these trucks to me modified...LOL

 

I would suggest, before spending a dime, spend some time reading. There is a ton of great info here. You can read about what several different people are doing and make a choice based on the responses of the people using the product. It's too easy to buy the first thing you see and be dissapointed later because you could have got something better for the same or a lower price. There are a ton of things out there for our F150's, many of wich are a waste of money.

Take you time. Spend a couple weeks here before making a decision. I think in the long run you'll be glad you did!

Welcome to F150 Online. You got money burning a hole in your pocket? Well you have somewhere to spend it soon enough!

 

Did you put in a GMS / Pro-M MAFS and have problems with it ?

Neal is the only one that I have seen state the GMS is crap, that a Pro-M is the prefered MAFS.
Oddly enough...the GMS MAFS is a Pro-M MAFS.
Pro-M and GMS make no bones about this, and it is posted on one or the other web site ( I want to say it is on the Pro-M web site ).

Aside from Neal's post, I have yet to find a post where someone had a problem with the GMS MAFS.

I was curoius how long you had the GMS MAFS on, and what you replaced it with. If you did not go with a Pro-M, what were the MAF flow rates on the mfgr that you installed ?

So far the MAF Flow Rates are looking good via my auto tap software. I get nice consistant flow rates at a constant speed, it does not jump drastically around the flow rate range.

I wanted to get your opinion on your problems with the GMS MAFS, before I put the stock one back on to compare it to, and so I know what to look for.
The drivability of the 5.4 seems to be greatly increased after the MAFS install. After 14-SEP I will have the dyno numbers for the truck as a whole, to find out where I am at.

 

I personally have not put on the GMS but have talked to several people, other than on this sight, saying that they are not as good as other brands, not*Crap*. I do not know about you but before I buy a product I like to find out what is the best one. By the way it was JDM not Pro-Comp,same people? Just like everything that I buy I read and talk to allot of people before I make that leap. If GMS is working for you then more power to you. I am sure that any after maket MAF from anyone would give you more gainsthan stock. As for GMS making MAF for other people I would be VERY interested in seeing that information. Bottom line LOOK BEFORE YOU LEAP

PS. Do not take this stuff so personal

 

BLUE Dog, i definately say go for a FIPK, you can feel and hear the power increase, but just don't get a K&N. I defintately say go for an Air Force One. At www.truckperformance.com they have the AF1 for 230 bucks, so why not for a couple, and i mean a couple bucks more, get the fipk that looks 100x's better than the K&N. The quality is top notch, its an easy install, and it makes a few more hp than the KN because the end of the filter isn't just capped off, it has an element there too.

not the best pic, it looks waaaay cooler in person, but you get the idea...



hope this helps, let us know what you decide

 

Harley, Thanks for the info, and the pic the AF1 looks awsome, thats a great price for that. You did notice a difference in hp, what exhaust did you couple along with it? I have an itch to MOD my truck in worst way, but this is a great site for different opinions.


Thanks,

Blue Dog

 

The exhaust is the stock harley edition exhaust, so it flows a little more than a stock 5.4L and sounds different, but i did notice it deepened the tone a little bit. And when you start up the truck or rev it, you can hear the air whoosh into the AF1, especially if the hood's open! And when you shut it off, it makes a sound like its discharging the air out. Very cool And i can definately feel a power difference when i get on it. Definatley a mod worth the money. You won't be disappointed!

good luck

 

It was a "GMS MAFS is a Pro-M MAFS", as in Pro-M makes the MAFS, GMS just puts their name on it. That is how the post reads, not the other way around.

The "several people" that actually used a GMS MAFS, what is the reason that they said "not as good as other brands". What did they replace the GMS ( again the GMS is a relabeled Pro-M MAFS ) with I hope not a Pro-M ?
How did they test the MAFS ? SOTP dyno ?
Strange how the post goes from you personally feel that there are better products then GMS, to several people saying that they are not as good as other brands. ???

JDM I thought just used the 90 mm MAFS, as in stock 01-02 L MAFS, and then the chip programing is changed to take this into account. I could be wrong about this, but the 90 MM MAFS needs programing to operate correctly above the 4800 RPM levels ( again this is what I recall, I could be all wet about that ).

Pro-Comp ? Did you mean Pro-M ?

I did do the research on the GMS / Pro-M MAFS, and it checked out, Also the Pro-M marked MAFS checked out, this stands to reason as they are the same thing.
The voltage levels I have not seen spike, and the flow rate is an even rate, not jumping around. This is via tha AutoTap software.

I did not take it personally, but now this is 2 cases on this topic of " I heard from this guy..." and the level of detail is it's crap, or in your case it is not a good product, without providing details of why.

I am only asking to find out if anyone behind these comments has ever given actual reason why. This is part of the the research for the next guy that is looking into replacing a MAFS, and the part of the information flow, without the blind reviews and generic results postings. This, and the K&N filter scare that seems to get posted about every 6 months or so about how it is a crap product is another example, with the lastest being the oil analysis thread.

Remember Info good, gosip bad...

I am always doing research, and this if there are any details on this, it gives me ( and anyone else that has a GMS MAFS ) a heads up to what to look out for. As the post states I have only had this installed since this spring ( about 4-5 months ) so if your "several people" had problems after 1 year of using it, this would be good to know.

 

Man you take this WAY too serious. Just a post from one guys opinion. Hey I have an idea why don't you spend all your money on all different kinds of MAF's and run all types of programs and dyno's and hundreds of hours and get back with me.

Thanks for all your hard work

Oh ya I forgot we are all building race cars.

In reality a camero with very little mods will whip a big truck with a ton of mods NOW THATS A FACT!!!!

 

Thanks for wasting my time with the past 2 posts.
I thought I had a chance to learn something new...guess it won't happen from your posts on this thread.

I should have known better then to ask, when the first post said "personally", again I thought I was going to learn something new. You seem to have an opinion about GMS products in general, that must be delevoped by speculation, without knowing who made the GMS part.

Actually a Camero with little mods will NOT whip all pickups with a ton of mods, is this another one of your origional generalizations ?
Remember a L is still a pickup. 11's is the best 1/4 ET I have seen on a L.....beefcake is hosting the video clip of this, you can get the link in the L forum.
There is quite a large club of 12.x sec trucks on this site.
Guess that is yet another fact that you developed somewhere ??
Want to try another FACT ?

 

You know I really considered to fire back with something but I think we are loosing sight

If you will please notice I say JDM. IS THIS THE SAME COMPANY AS PRO-M? I still have not seen you post anything from anywhere that says that GMS is made by pro-M. I would really like to know for a fact. I would really like some other feed back if anyone truely knows which is better instead of this **** fight. More than likely true hard numbers are not out there but I will ask.

To anyone that may post it is okay to have an opinion I really do not care if you have dyno slips or any of that stuff just one persons feeling on the matter at hand.

It does appear to me that the JDM is a little cheaper than others.

Lets stick to the subject.
