        Best tuner for 2.7 with big tires

        I have a 2015 f150 2.7 on a 6inch lift with 35s, before the tune my truck was slightly sluggish and needed the speedometer recalibrated and gas mileage was 12.1. I found this tuner and did my research and installed it which took 15 mins. It’s super easy. My speedometer read correctly. Truck ran perfect with the 35s on now. The HP and torque increased and you can definitely tell. There’s 3 pre-set tunes. My MPG is now 15.5 and slow increasing which is great.

        Perfect for putting the zing into your F150 Ecoboost. The best thing is that you can use it over and over and program as many parameters as you need to with the custom programming software available from the vendor.

        Initial high hopes, dissappointed in the end

        So the tuner itself is nice. The display is big and bright and easy to read. The features it has already pre loaded onto the tuner were only an option to change my tire size which was one main reason I purchased it. The initial setup on the computer is straightforward, then plugging into the truck and installing is straightforward and easy. I was dissappointed that it doesn't come with any preloaded tunes. Because now you've bought this unit and the only thing I accomplished with the $400 invested was calibrate my speedometer, in which case I could have spent half the price for a competitiors tuner. Something that shoppers should be aware of is that the investment does not end at $400, that's your starting point. It's $400 paying for custom tunes to install on your truck. That's where I am dissappointed because it is misleading in the sense that it tells you all the features but nowhere states you won't have any tunes on the tuner and also I believe they (sct) need to specifically releases what all features are availiable for this truck specifically because you see a long list of options and at the bottom, yes it does say not all options availiable on all vehicles but overall, it was dissappointing.

        Not all it's cracked up to be

        Pros: Does increase some noticible HP and torque. Cons: 1st off, the SCT X4 doesn't have "free tunes" available. Once you program it, your stuck with that tune. Heaven forbid you made a mistake! Then, it doesn't give nearly enough options, like adjusting for a cold air filter system, increase in boost, rearend ratio changes, headers, high-flow cats, etc.

        Great tuner. Instant power gains makes your truck feel like a different beast. Easy to download program to computer and load tunes. Preloaded tunes work great as a start out upgrade. Highly recommend this tuner.

      Will this tuner help my truck with the power to pull my 29 ft travel trailer.

      • While the SCT SF4/X4 Power Flash Tuner will improve horsepower and torque, it will not necessarily increase your towing capacity.

      I travel quite a bit, I recently switched from QT to Shell and am seeing better mileage, on highways 22 to 23mpg. Since I'm on the highway so much what can I reasonably expect my mileage to be... Of course can't hold you to it, but would it be worth it to me to spend 500 on. Would/could it pay for itself in fuel savings?? Thanks

      I purchased this unit a little over a year ago for my mustang 5.0. I no longer own the mustang and did not unmarry the unit from the car. I still have the unit and want to know if I send it in can it be unmarried and then used for a 2.7 liter ecoboost f150. that I now have?

      • This can be used on the truck however since it is married still you will need to send it to SCT to have them unlock it.

      Does this tuner have the ability to turn off o2 sensors for a cat less down pipe?

      • You will require a custom tune from a tune shop that is willing to disable O2 sensors in order to turn off the rear O2 sensors. At this time we are unaware of any tune shops offering this service.

      I have a 2015 2.7L EcoBoost, and recently bought this tuner in hopes of increasing my mpg some. I use 87 octane gas so that was the option I chose when programming the tuner. Is this the option I should've chosen? I just want to make sure that I get the best fuel economy I can using this tuner.

      • When selecting the octane rating for the tunes with your SCT SF4/X4 Power Flash Tuner, you should select the fuel octane you plan to use. Higher octane fuels will result in higher MPG's but the increased fuel cost will make this a less economical cost
