I have a F150 Supercrew 4.6l 2WD I just lifted with a 3.5 spindle and added 285/75/16 and of course have loss horsepower and Gas Mileage. I'm curious as to what the best chip would be to purchase at a reasonable price that will help me get the best gas mileage and increase the horse and torque. Also would like to try and keep the factory warranty

Also where could I get this chip?

Thanks

Good luck and have fun !

 

No chip will kep your factory warranty. The best for you would be to use a Flip Chip or Microtuner that allows a quick change to stock program for any warranty work.

The best performance comes from the 9100 Microtuner.

 

Hi lvchris,

The best power & performance gains are had by having us (meaning us here at Troyer Performance) do a custom tune in a Micro Tuner, that's what most people are doing these days. The Micro Tuner is a plug & play hand-held flash device, rather than a traditional "chip" - that way you have an easier & shorter installation, and end up with no diagnostic or datalogging limitations as you have when using a traditional performance "chip" in Ford vehicles with EEC-IV & EEC-V PCM's.

What you have done to your truck is a very common scenario, one that many owners do with these trucks - install bigger tires & lift it up a bit. In addition to making it like you want it, as you already know what you have done also resulted in reducing torque multiplication by installing 33" tires (well, 32.8"), and you have also increased it's aero resistance/loading by lifting the vehicle. That's a real "double-whammy" to your truck's performance, and has also thrown off the speedometer, the transmission shift points (you may not have even noticed that at all), hurt part-throttle driveability and it's fuel mileage isn't what it could be - but of course, you already know all of that.

In your case, your tires spec out at 32.8" tall, so you should be fine just having us do a custom tune in the Micro Tuner for you - there will be enough power & performance gain, along with fixing the speedo, Odo & shift points, removing the top speed limiter, etc., that you will once again be able to enjoy driving the vehicle without having to pony up big bucks for a gear ratio change. That is usually what most people in your situation do, meaning those running a 33" tall tire or less, they usually don't do the gear ratio change, but instead will have us do a performance tune for them to pick up some power & help restore performance.

You can read all about this here in this section, and you'll see many people who are using our tuning - most F-150 owners tend to come to us for their tuning needs, as we have specialized in performance tuning the F-150 for 12 years, longer than anyone else.

With regard to the effect on your warranty, by law you are allowed to do whatever you want to your vehicle, as long as what you do to it does not actually cause *damage* - that is what the Magnuson-Moss Warranty Act provides for, a basic set of fair play rules that protect the automaker and the vehicle owner from each other. What happens under warranty is by law a matter of what's fair, though some dealerships will go out of their way not to do work under warranty, simply because the automakers (not just Ford) pay the dealership far less than what they make if the customer has to pay out of his own pocket for the exact same work. This is why it's important to know what your rights actually are, & you can get all the independent & accurate info you need on this by dropping by this web site: www.sema.org

Here is the specific link at our site to read up on the custom-tune capable version of our Micro Tuner: http://www.troyerperformance.com/cgi...catalogno=9100

That is what I recommend you use, as that will provide you with a simple 10-minute plug & play installation, as well as actually get you the very best power gains & performance results, etc. This is what most people here now are having us do, a good custom performance tune (even on a bone-stock vehicle) in this version of the Micro Tuner. You'll have more HP & torque all the time, at any throttle position, and at any rpm.

Please feel free to give us a call at our number listed below to go over all the various details, options, specific power & performance gains, costs, etc. - we'll be happy to spend some time going over all of this with you so you'll know everything you need & want to know about doing this.

Best of luck with your truck,

 

Thanks for all the help. The 9100 you have mentioned, which Octane is needed? The truck is a 2003

Also is there a big difference between the 1715 tuner and the 9100?

 

The 9100 gets you three custom programs. Most people want an 87 octane program, a 91+ towing program and a 91+ non-towing program, similar to the 1715 microtuner.

The 9100 is about $75 more than 1715 and can yield up to 50% more performance inprovement over the 1715.

 

Hi lvchris,

In the 9100, we can set it up for any level of octane use you want - it's completely custom, so we can do any configuration of 3 different tunes, any way the customer wants them.

As APT mentioned in his post, what most people have us do with the "regular" F-150's that are daily drivers & occasional tow vehicles (perhaps the most common uses of the F-150) is to have us do a 3-program setup very similar to what the 1715 has - meaning, a program for use on 87 octane that is towing compatible, then a program for premium gas that is also towing compatible, and then finally, a "MAX" performance tune for premium gas that is *NOT* towing compatible, as it's for maximum performance. That is the most popular & usually the most applicable 3-program setup in these trucks for the 9100 - but we can actually do it any way the customer wants, of course.

Some people want all 3 programs for towing, 87, 91 & then 93 octane - some are drag racing, and will want 1 program for use with 100 octane race fuel, for another example. It's all a matter of the vehicle, it's mods and how it's going to be used, basically.

In terms of how much more power we can get from the 9100 as compared to the 1715, in the V8 F-150 it's going to be a minimum of about 10-12 more HP and in some of them, even more additional gain over what the 1715 delivers - it's just a matter of each truck's actual computer code and just what kind of shape it's in from the factory. Figure that in terms of the actual amount of *additional* performance improvement in the 9100 over the 1715, we can get roughly about 30%-50% more performance gain over what the 1715 delivers, on average.

But of course, keep in mind that the 1715 does cost less, and it already does a fine job in these trucks, with many people using them. The 9100 is intended for those who actually *need* custom tuning - but can also be used by those who want custom tuning to get maximum power & performance gains, even if the truck is bone stock - or for 4.2 V6 owners for example, as for them that is the only way to get into a Micro Tuner. It's not like you *have* to use the 9100 over the 1715, it's just available for those who want to spend the additional $$ to get *maximum* power & performance gains.

If you'd like to go over this in more detail, give us a call at our number listed below & we'll be happy to help you.

 

Thank you both for the help, I think you and APT have me sold on the 9100. I'll be calling you in the next few days to have mine ordered.

Thanks

 

You're very welcome, anytime!
