I have a 2004 F150 lariat supercrew i was wondering if i installed the 1715 Micro Tuner would i get better gas mileage are the same are not as good. And also would it mess with the computer that lets you know the mileage you are getting THANKS

 

The 1714 is the unit for the new 04. I installed mine today. I will post my findings in the next few days. It will help with the MPG as well as make noticable imptovements in your computers programming. The best price is through Mike Troyer with a f-150 online log-in name.

 

Thanks for the reply i would like to make horse power but i don't want to sacrifice the mpg. thanks for what imformation you can provide

 

If you want to keep or improve you MPG... stay with the stock tires.... or at least the stock size. The 1715 will help you MPG. As far as the exhaust and cold air intake... you may ask other more knowledgable people. The tuner will help!! You can choose either 87 or 91 octane.

Good Luck.....

 

Thank you for your reply, How do you like the 1715.Do you really feal the diffrence in the truck in power and re-action time. I'm also thinking the under drive pullys. I haven't seen much down fault in it in my readings. Have you tried the under drive pullys ?

 

The 1714 is actually the model number for the new 04 F-150. I've had the 1714 installed for two days now. I set it up with the 87 octane bacause I had a half tank of 87 at the time of the programming. I feel the biggest difference in the shifting. Its my understanding it takes a little while for the program to setup... meaning it should only get better as time goes by. If you're wondering if I feel the 1714 is worth the money... "yes" I do.

I'd like to do the pulleys and electric fans, but I believe it fairly expensive. I do phone work... not automotive. It would be different if I could do the installation, but I can't.

Also K&N finally came out with a intake kit for the 04. I have the true flow, but would rather have the K&N.

 

Hi Tony,

The 1714 Micro Tuner is not going to cause a decrease in MPG UNLESS you drive the vehicle harder after installing it than you did before installing it - or you use a lower quality fuel with a lower energy content (# of BTU's per gallon). Now that is something that a lot of people will do after installing a performance part - meaning driving the vehicle harder checking out the new performance levels after installing a new performance part - then once driving returns back to normal, then most people do see some increase in MPG from the 1714's tuning.

Just to give you a rough example of what some of these parts can do, in our 2004 SuperCrew Lariat 4x4 we have our electric fan kit, underdrive pulleys, tuning, headers, cat-back exhaust system and ignition upgrade - we're out in the mountains so our driving is constantly up & down the mountains, not very good for fuel economy. In stock trim, the truck got anywhere from 12 to 17 MPG, and now it usually ranges from a low of about 16 MPG to 23+ MPG on the highway in it's current configuration.

Now to be clear, it can't deliver an overall AVERAGE of 22 MPG of course - that's just what it currently gets on the highway cruising at 70-72 mph with the A/C on, on level terrain - cruising at 65 mpg with the A/C on and driving on level terrain, we've seen as much as 23.5 MPG - the 2004's are bigger & taller, so as you increase speed, the MPG drops significantly - a bit quicker than it did in the 1997-2003 models, for example.

Our overall average for the last couple of tanks (and it's been driven a bit harder as we've had to do some hustling & testing lately again) has been 17.0 overall - and that's in the mountains at elevations ranging from 2200-3500 ft. For a truck weighing 6200 lbs. *empty*, that's pretty darned good, especially compared to stock.

With regard to the #1714 Micro Tuner you would need for your 2004 truck, the MPG gains cannot be guaranteed, as it's a performance part - not really an "MPG" part per se. But the vast majority of owners do see some MPG gains on the premium-gas programs when they keep their foot out of the firewall, so to speak, and that is due in part to the increased spark advance used on part-throttle, as well as some other changes. The MPG gains on the 87 octane program are maybe 0.5-1.0 MPG, with gains on the premium gas tunes running more like 1.2 - 2.3 MPG - now keep in mind that this is going to vary a bit based on just what kind of configuration your truck is. For example, a SuperCrew 4x4 Lariat w/ the 18" wheels & 3.73 gearing is over 3 tons of weight empty - significantly more than say, a 2WD short-cab with the same engine & transmission & gear ratio - you get my point.

With regard to the use of underdrive pulleys & Electric Fan Kits, we offer both for the 2004 F-150. The MPG gains from underdrive pulleys are roughly about 0.5 to a maximum of 1.0 MPG, while the gains from converting over to electric cooling fans runs about 1.2 - 2.5 MPG. The combination of our e-fan kit & our underdrive pulleys nets you upwards of 25-30 more HP to the rear wheels, and a nice MPG gain as well - so those are always great mods as they get you both more power at the rear wheels *and* an improvement in MPG, too.

One note on MPG - we're coming up on the time of year when various areas are going to start phasing in "winterized" fuels a they do every year before much longer, so do your MPG comparisons during the same season, so they aren't skewed by the always lower MPG you get in winter from those oxygenated gasolines. Figure you'll usually drop about 10% in MPG in winter over summer fuels, roughly.

We specialize in the performance of the F-150 platform, and have pioneered a number of the performance parts available for the 2004 F-150 - if you'd like to go over any of this in more detail, get exact costs, installation times, etc., or just want to go over anything performance-related about your 2004 F-150, please feel free to give us a call at our number sited below & we'll be happy to help. For some quick info, you can drop by our web site at www.TroyerPerformance.com

Congrats on your new 2004 F-150, you should enjoy it for many years & there is *plenty* of additional performance and even fuel mileage that can be had in these vehicles.

Good luck with your new truck, & we hope to speak with you at some point!

 

This is outside the general thread but I have twice in a month's time run trips of over 200 miles through mountian country with my 02 Screw 4x4.
Specifically with the tail gate down, it does wonders for fuel milage even beating at 75 + mph most of the time giveing an average over 17 mpg.
It seems to have a great effect on this truck.
The motor is the 4.6, 4r70w trans , 3.55 and no changes to any part of the truck.

 

I once read that having the tailgate up can HELP the mileage. How? The airflow comes over the top into the tailgate causing a over the top spin. Something like a golfball being hit on top which cause it to spin farther down the fairway. Almost like the air is hitting the tailgate and pushing the cab forward. I have no idea if this is true, but I think the article was in one of the 4x4 mags.

I wanted a tonneau cover, but didn't like the idea it can only be opened so high. I found this item and feel I got the best of both worlds. It's remote and I VERY happy with it.

I have a '91 5.0 302. I was wondering if there was any chip I could put in there to give it a boost. I called a local parts store and they said they didn't have anything like that.

I also have a '95 7.3 turbo diesel. What type of chip would you recommend for that?

 

I did do a search, too. Couldn't find anything.

 

Look at it this way for bed and tail gate.
When the gate is up, the air across the top of the cab does indeed swerl in the bed causing a vacuum (negitive pressure reduction) in the box area.
This can be proven by laying a piece of large area cardboard on the bottom and going out for a run. Watch when the vacuum generated picks up the piece and is caught the main air flow and flies away.
Now go on a bit further and say there is a two pound negitive pull at that time.
Take the area of the card board and times by the pull force and you can see there can be substantial suction ( the whole bottom of the bed) that acts on the whole truck trying to pick the rear up as well as affecting the amount of power increase it will take to keep the truck moving forward.
The NASCAR cars use a spoiler to keep the rear down (acting like a tail gate) at the very high speed they run and argue about as little as a half in height change.
Drop the gate and much of this effect goes away.
Addmittedly I gave a half assed discription of the action but it is the way it works.
I can also relate to another proven example involving a bit different air action.
We towed a sprint car with the wing angle up at about 18*. The tow driver is use to pulling a much heavier back-hoe machine. He commented the race car was harder to pull over 40 mph than the much heavier back-hoe machine.
On the way back home we flattened the wing to 0 effective angle and he saw the difference right away.
So the differences in these seeming little things have a larger effect than most would believe.

 

Hi Robby3_15,

This section has plenty of posts about our chips for both the F-150 and the Powerstroke diesel. Doesn't matter what model year, as we tune all computer-controlled F-series & PSD's, so we can help you with that.

Take a look at the following link & you'll find the info right there on chips for both of those vehicles: http://www.troyerperformance.com/cgi...chips%3BFoMoCo

At that page, your F-150 truck can use any of the following Part#'s you will see listed: 1100 (single program single-bank chip with "standard" performance tuning), 5500 (single program 4-bank chip with in-depth custom tuning), & 6600 (4-program 4-bank chip with custom tuning). For your 1995 PSD, you'll want to use our Part# 1200, which you will NOT see listed there - but you can read up on the power gains from the chip for your 1995 PSD by reading up on our Part# 1705 at that same page (that's the flasher for the 1996 & newer 7.3 PSD's), and you will see a paragraph that talks about the 1st generation PSD engines, which are the 1995-1998 model years - you'll see the power & torque gains for those model years listed under the info for Part #1705, even though it's our Part# 1200 that you would actually use for the 1995 PSD, as it's not fully OBD-II compliant.

To go over any of this in more detail (and I know some of the above can be confusing!), please give us a call at our number listed below when you get a chance & we'll be happy to go over all of this with you in proper detail, for both of those vehicles.

Glad to see someone making these vehicles last - good luck with them & we hope to hear from you!
