I recently put 285's on my truck and noticed the accelaration is noticably slower from a takeoff. I was thinking of adding an Xcal or Edge but I'm not sure if I would be wasting my money since the only mods that I have are straight pipes and a drop-in K&N air filter? Basically I'm just hoping for 1-2+mpg without damaging the motor at 141k miles. Any advice would be appreciated.

 

Simple answer? Of course.

I don't have any performance mods except for the Edge and it works great. Others have some mods and the Edge works great, and others still have many mods and the Edge works great.

 

What about my mileage at 141k though?

 

ditch the straight pipes for a single 3" magnaflow or something else straight through, you should pick up a mpg over straight pipes

the programmers wont really net you anymore power unless you drive like a grandma full time

 

Honestly, I don't know. My MPG went up 2-3 but with your truck its a completely different tuner and I only had 8K. I'm sure one of the beta testers will chime in soon.

 

i noticed no mileage difference with my edge to my superchips. with either of those i got half a mpg over stock

 

I haven't experienced a great MPG increase with my Edge, but it does have more power and some nifty guages, and timers.

The built in code reader is sweet too. It diagnosed my problem while I was driving down the road. I had a vacuum leak and it kept throwing codes and making my check engine light come on. Whevever I couldn't stand to look at the light anymore, I just pressed 3 buttons and it went away.

 

I would consider going back to single exhaust except I just spent almost $300 for my dual set-up two month's ago. I've been through the whole modding bug with my Mustang (and still have it bad) now I'm just trying to find out what works well with the truck?

 

You might want to consider custom tuning. You’ll get the biggest hp & torque gains

 

since putting in my Edge I have seen a 2 mpg increase...

 

Would I be able to adjust shift points & firmness with either tuner?

 

Yes the Xcal2 and EDGE both can change shift firmness

 

How much are you guys paying for the Xcal2 with the 3 tunes if you don't mind me asking?

 

we can not post about pricing your best bet is to call a distributor, I got my truck tuned by www.troyerperformance.com check out there site or just give them a call they are great people!

 

Hi J_C,

As another poster mentioned, we cannot discuss specific pricing here in this section, it's against the rules. However, we *do* offer a special F-150 Online member discount which you can get by simply calling us at our number listed below, and our Troyer Performance custom tuning will deliver the best power & performance gains - we can also do, for example, an MPG-specific type of tune.

Now with 141K miles, you are still safe to do modifications as long as the engine is basically healthy - you just need to make sure that your maintenance is all up to snuff - spark plugs, fuel filter, upstream O2 sensors, etc., otherwise your results, no matter if you are stock or tuned with anything, will not be as much as they could be.

Also, running "straight pipes" is really not the hot tip - all that does is create a lot of noise, and serves to reduce part-throttle torque even though you do pick up some full-throttle horsepower - so that isn't helping fuel mileage either. I'm assuming you just ran dual straight pipes back from the cats, I hope you didn't yank the cats off - that would be illegal but more important to your concerns, would actually reduce part-throttle torque & fuel mileage due to the reduction in cylinder scavenging from pulling all of that heat from the cats out of the exhaust stream, as it creates additional exhaust gas velocity. If you are running straight pipes, you might want to think about installing a pair of Magnaflow mufflers, which is not expensive, at some point - or, there is a single larger Magnaflow muffler that is one unit but is true dual in and out that would work very nicely for you, as it also has an X-pipe incorporated into it, and that would give you better torque and MPG as well - this is just FYI so you'll know.

And of course, as long as it's a 1999 or newer truck, we can recalibrate the speedometer for you so it reads right (which will fix the odometer and shift points in the automatics, too) in our custom tuning. For 197 & 1998 trucks, you need to do a simple speedo gear change which is easy & cheap.

The bottom line is, the best potential for tuning is had thru our custom tuning, as we have specialized in tuning the F-150 platform far longer than anyone else, and actually help a number of the major chipmakers with their F-series applications as a result of our expertise on this platform.

I hope this brief info helps, & please feel free to give us a call if you'd like to go over any of this in more detail!
