Tuners will tweak your engine’s performance to optimize fuel per mile ratios by using specifically canned or Dyno tunes. These will ultimately deliver an improvement of anywhere between 1-2MPG, which over hundreds or thousands of miles accounts for a lot of saved money.
A good tuner that comes with preset tunes, will provide your engine with overall better performance, as well as give you a more intuitive converter lock-up strategy with increased line pressure that makes for better clutch holding capacity, quicker shifting, longer trans life and also lowers the overall temperatures, for power you get increased torque and better kick down response.
SOTF (Switch on The Fly)
You might have heard of this, and for the Ford 6.7L trucks SOTF is actually a very popular and sought after features What SOTF does is it allows you to match powertrain output to truck usage. For towing heavy loads, this is a must, since you can assure a non-compromised power curve when pushing uphill, this will maintain temperatures and torque loads to transmission.
Emission Equipment Deletion
You should not tamper with emission equipment performance, it is both illegal in many states and will take away a lot of the warranty work requirements. Essentially, there is a lot of misconception about factory emission equipment, and most of it is bull, so just ignore the idiots that cancel out DPF, DEF, EGR and don’t be fooled into deleting them.
Voiding your warranty by using a tuner is an issue that is usually handled by the dealership or insurance company policy you have. Consider this, check it out first, if your warranty is still valid, don’t void it recklessly, check first.

The Ford 6.7 Powerstroke engine was created in 2008, with the code name Scorpion, this exceptional engine changed the way to next-generation powerful diesel engines, and it took a year of intense planning, design, and testing to come up with this new engine for their F-series of trucks.
In 2010, The first 6.7L Powerstroke engines came with 390 horsepower, and this was increased to 400. In 2015, the upgraded model was given 440 horsepower and provided 860 lb-ft of at 1600 RPM.
This 2015 model comes with 3.9” bore cylinders and a 4.25” stroke, and as the name suggests, the engine’s volume is 6.7L, which is 409 cubic inches.
Head and Block
The 6.7L Powerstroke engine block is now made out of compacted graphite iron (CGI). CGI is a more popular material due to its increased strength and lighter weight when compared to the traditional cast iron blocks. CGI was initially used for brake discs on high-speed trains.
To reduce weight and increase thermal transfer performance, the head is made of an aluminum alloy, and this comes with 2 intake and 2 exhaust overhead valves (OHV) per cylinder valvetrain. The camshaft is located in the block and uses the traditional pushrod strategy.
The decision to move the turbocharger into the engine valley, as well as change the block to CGI material was at first met with skepticism. However, these two changes, together with the new fuel injection system, revolutionized the diesel stereotype from a boorish dirty image into a competitive hi-tech market.
The 6.7L Powerstroke leaves the factory with the following specifications:
- Block: CGI
- Bore: 3.90 in
- Stroke: 4.25 in
- Compression: 16.2:1
- Cylinder Head: Aluminum
- Valves per cylinder: 4
- Turbo: Single Sequential (GT32)
- HPFP: Bosch CP4.2
- Injectors: Bosch Piezo
- Initial Horsepower: 390 hp
- Initial Torque: 735 lb.-ft
- Adjusted Horsepower: 400 hp
- Adjusted Torque: 800 lb.-ft
Now that we have an advanced composite diesel engine, and yes you can use the word composite for anything that is made out of more than one material., makes it sounds so much more sophisticated than it really is. Let’s take a look at how we can improve its performance, which is what every truck driver want to do, even if they don’t admit it.
Before you consider upgrading your engine with aftermarket parts, take note that a tuner will improve performance that might meet your requirements, and save you on aftermarket upgrades. On the other hand, you might want a complete upgrade with aftermarket and tuning. This will turn any 6.7L Powerstroke beast into a rampaging Hulk.
What can be tuned?
You can tune any part that is electronically controlled by the PCM. This includes:
Camshafts, Cold air intakes, Cylinder heads, Fuel injectors, Full exhaust systems and headers, Intake manifolds, Nitrous systems, Rear gear changes, Superchargers/Turbochargers, and Throttle bodies.
This is the performance list, there are other options to add such as automating windows, locks, alarms, etc., but that is for comfort, not performance.
Take heed that tuning your Powerstroke will void its warranty, and understand this, Ford has proprietary software that will know when you tuned, and how many times you tuned and restored.
Custom, Canned and Dyno
There are three types of tunes available, these are:
- Canned: A generic preset tune that comes with the device.
- Custom: A specially written tune, either prepared by a company or made by a professional.
- Dyno: A shop prepared tune, where the tuner dials it in in real time.
Please be aware that you must never buy a tune from an unknown source, and never tune by yourself. Custom tuning is for professionals that understand the nature of the entire operation; one change can destroy your performance, let alone an entire range of changes.
There are two variants for programming; one is the use of chips, which come with preset tunes that you can employ at the flick of a switch. These are closed circuits, which means you cannot make custom adjustments. The second variant is Tuners, which come with open circuits that allow you to make custom changes to specific options.
Now that you have the basics on tuners, how will they affect your 6.7L Powerstroke?
Mileage relates to how efficient you burn duel, and in this case, we have a few issues to contend with, these include, such factors as driver habits, average road speed, idle time, ambient temperature, braking and more.
Consider that a single wheel truck provides 16-18 MPG on stock tires when managed by an aggregated driver with an aggregated load.
