I have an 06 fx4 SCREW. I added K&N cold air intake as well as flowmaster 40 cam back. Before I knew anything about this board I bought a Superchips Hypertech. I am running 93 octane and the Performance setting. I honestly don't feel that much of a difference with it from stock. It is much louder on the freeway with the tuner at performance then at 87 setting. The shifting is smoother but that's it. I also feel that when I am around 70mph and let off of the gas, almost like I am slowly putting on the brakes. I don't have a great mechanical knowledge base but I am not sure what to make of this. Any sugestions would be appreciated.

I did call the place I purchased the Tuner from and they said call superchips. Superchips was no help at all.

I then called Troyer Performance a lady told me that can happen with the limited capabilities of the superchips tuner. She recomended a custom one but I already have money in this one. Also she said i would need to dyno test and I can't find anyone around me that would dyno my truck. They only do bikes they say. So I don't know what to do. I am posting becuase it seems that a lot of people here have a great wealth of knowledge about this stuff.

 

I recommend the TP custom tuned XCal2. I’ve been running Mike’s tunes since 04 and they’ve been great

 

that's what the lady told me when I called. She also said I would have to get a dyno test and there is nobody in my area that does it. Anything I can do with what I have bought already? If not then according to this lady I spoke to at Mike's, I can't do the Xcal.

 

I assume you are somewhere in the Carolinas by your name. Where are you located? I am in Raleigh, NC and just searched Dynojets website and there are a plenty of dyno's in my area.

I am in Charlotte and the numbers I called on that list are either no longer doing it or only work with bikes.

 

carolina-06fx4 the reason TP is emphasizing the dyno is because of your K&N air intake. 04 and up F150’s use a MAS instead of a meter to measure the A/F ratio and if not properly setup, will run lean whereas with the AF1, (the intake kit that shows the largest hp & torque gains) there’s less guess work because of the extensive R&D and thousands of XCal2 & AF1 combos already in service.

The AF1 would be optimal, but I think your K&N will work just fine with custom tuning but the A/F ratio needs a careful look to make sure everything is properly setup.

There’s an alternate method of data logging the A/F ratio with the XCal2 using SCT LiveLink software. When you talk to Mike ask him about it.

Bottom line is, TP’s custom tunes are dabomb and it’s the way to go IMO

 

Thank you for your response. I have no problem in trying to get this right. I am just trying to avoid loosing to much money. Since I was told today to change out my flowmaster 40 to a magnaflow I am just confused. I checked the price here for getting and installing the magnaflow sido and it was over $800. Now I already have a little over 4 in the flowmaster. If I were to swap out the K&N airflow with an AF1 would that help me here?

 

also, is there a big difference between the K&N and AF1

 

If you leave your Flowmaster on, you’ll be OK. The Magnaflow supposedly gain a couple of more hp but not enough to make any difference you’ll be able to feel IMO.

You need to call and talk to Mike about your XCal2 custom tunes. I think you’ll find that the K&N & Flowmaster are still serviceable just not optimal, but exactly what the hp & torque difference is, I don’t know.

 

This guy is a walking, talking commercial for Troyer huh. j/k

 

Dude, you don't need to swap out the K&N Cold Air intake or the Flowmaster.

My truck is an 05 Screw with 5.4. I have the same setup as you have. I have KN intake and Flowmaster Dual In/Dual Out system. Just tell Troyer what you have and he will set you up with what your applications are.

You don't need to change to AF1 or Magnaflow exhaust like some of these guys are telling you. Your horsepower gain will be minimal. There is no use in spending $1,000 for a 5 plus or minus horsepower gain.

Also, you can try to sell your tuner using the Classified at the top of the page. I sold my Superchips 1745 tuner and got nearly what I paid for it.

My truck runs well on Troyer's XCal2 tuner. I am very satisfied with it.

 

K&N is plastic and the AF1 is metal. If you are going for looks, then AF1 is the way to go. I like the look of the AF1 but cost wise it would not benefit me to spend $400 to get a minimal at best HP gain. Since you already have the KN installed, I would leave it on and just go on.

 

Now that sound more like it. It gets very confusing having a couple people telling you different things. The lady at Troyers was telling me that I should change out the exhaust and possibly the intake to get the Xcall 2. Not have to but would be reccomended for the performance I am looking for that eveyone is talking about.

I called Superchips to try and find out about returning mine and they said they have custom files they could send me for the Flashpaq that would be as good as the excall 2 custom. Not sure what I make of that at all!

 

The nice lady is a salesperson. She wants you to buy this because it helps the company, I completely understand. But the performance gains are not that huge from one setup to another.

For instance: I had a Flowmaster Dual in Dual out on my truck when I got the XCal2. I have since changed it to the Magnaflow Dual In Dual Out exhaust just to see if there was that big of a difference. I didnt notice any difference other than the cab noise being a little less with the Magnaflow.

I called Troyer Performance before I actually changed from one exhaust to another to ask them if I should get my truck retuned because of the difference. I was told that I didn't need to make any changes to the truck, it would be fine.

So apparently the tuning is not that big of a difference from a Flowmaster to a Magnaflow. This is just my personal experience.

They are just trying to get you to spend more money.


SCT XCal2 is actually a Superchips product. SCT stands for Superchips Custom Tuning. Mike Troyer has been tuning F150s longer than anyone in the nation. He helps Superchips with their Research and Development. I would stick with Troyer and buy a Custom Tuned XCal 2 from him. I wouldn't trust anyone else.
