Memo Tuning and Performance

Memo Tuning and Performance: making the hardware actually pay off
Memo Tuning and Performance is about calibration, the step that decides whether the parts you bolted on actually do anything. A modern engine is run by a computer, and the factory calibration is written for a broad range of fuels, altitudes and drivers, which means it leaves margin unused. A proper tune releases that margin on a turbo engine, sharpens throttle and shift behavior on any engine, and corrects the fuelling when an intake or exhaust changes airflow. We do this with a dyno and with data logging, so the result is measured rather than guessed. This page covers how tuning works, what fits what, the dyno process and what it costs.

- Biggest gain on turbo and supercharged engines
- Corrects fuelling when intake or exhaust changes airflow
- Measured with a dyno and data logging, not guessed
Tuning fitment by engine platform
Tuning is engine-specific, because each platform has its own computer, its own sensors and its own limits. A Ford F-150 EcoBoost, a Chevy Silverado 2.7 turbo, a RAM 1500 inline-six, a Toyota Tacoma turbo and a Jeep 2.0 turbo all gain strongly from a tune because they are boost-controlled. A V8 like the Silverado or Sierra 5.3 and 6.2 or the RAM HEMI gains response and shift quality but less peak power. A naturally aspirated V6 gains the least in absolute terms. Diesels are tuned carefully because emissions controls limit the change, and we tell owners honestly what a given platform will allow before taking the job.

Tune types and what supports them
There are three common paths. A canned tune is a pre-written file loaded from a handheld, which suits a stock or lightly modified truck. A custom street tune is written for your exact hardware and verified with data logs. A dyno tune is developed on a load-bearing dyno and is the right choice for a modified or boosted build. Supporting hardware matters: an intake or exhaust changes airflow and the tune should be written for it, a colder thermostat or intercooler upgrade helps a boosted engine hold its gain, and fuel quality sets the ceiling. We match the path to the build rather than defaulting to the most expensive option.
- Canned tune from a handheld for a stock truck
- Custom street tune written for exact hardware
- Dyno tune developed under load for modified builds
- Supporting hardware like intake, exhaust and intercooler
- Fuel quality that sets the safe ceiling
How a dyno tuning session runs
A proper tuning session is a sequence, not a single flash, and we follow it so the result is safe and repeatable.
-
Confirm the engine, hardware and fuel being run.
-
Pull a baseline dyno run or data log on the stock calibration.
-
Review the data for fuelling, timing and knock limits.
-
Write a first calibration for the installed hardware.
-
Run it under load and read the data again.
-
Refine across several runs until it is smooth and safe.
-
Hand over the file and show the owner the before and after.
What tuning costs
Tuning pricing varies with how it is done. A canned handheld file is the cheapest, a custom street tune sits in the middle, and a full dyno session costs the most because it takes time on the rollers. Supporting hardware adds its own cost, and a boosted build that needs several revisions costs more than a lightly modified one. We quote the tune and any parts separately, and as ranges, because the number of dyno runs depends on how the engine responds. Read every figure as a range until we see the truck and its hardware.
- Handheld tuner with a canned file
- $430–$900
- Custom street tune with data logging
- $600–$1,200
- Full dyno tune session
- $800–$1,800
- Supporting intake or exhaust before tuning
- $280–$1,700
- Additional dyno revisions for a boosted build
- $150–$400
- Diesel tuning within emissions limits
- $500–$1,200
Who gets a tune, and why
A tune is bought for different reasons. Owners who just added an intake or exhaust buy it so the engine takes advantage of the airflow instead of running a stock map. Owners of turbo trucks buy it because it is the single biggest gain available. Truck owners who tow buy it for firmer shifts and better throttle under load. Diesel owners buy it for torque within the limits the emissions system allows. Enthusiasts buy a dyno tune to finish a build and see the numbers. In all cases the tune is the step that turns hardware into a result, which is why we treat it as the centerpiece rather than an afterthought.
- Owners who added intake or exhaust and need a matching map
- Turbo truck owners chasing the biggest single gain
- Tow truck owners wanting firmer shifts under load
- Diesel owners wanting torque within emissions limits
Street tune or dyno tune, honestly
The choice between a street tune and a dyno tune is about risk and budget, so we explain both. A street tune relies on data logs from real driving, and on a lightly modified truck it can be excellent value. A dyno tune develops the calibration under controlled load, which matters on a boosted or heavily modified engine where a bad run could hurt the motor. If your build is stock or mild, a street tune is often enough and we say so. If it is boosted or has significant hardware changes, a dyno session is the safer path, and we would rather do fewer expensive sessions than risk the engine to save money.
- Street tune: logs from real driving, great value on mild builds
- Dyno tune: controlled load, safer on boosted builds
- Mild builds often fine with a street tune
- Heavily modified engines want the dyno

Questions about this part
Do I need a tune once an intake and exhaust are fitted?
It is strongly recommended, because the airflow has changed. Without a tune the engine runs a stock map and leaves the improvement mostly unused.
Will a tune void my warranty?
It can affect the powertrain warranty if the failure traces back to it. We explain that honestly and keep the factory calibration so the truck can return to stock.
How much power does a tune add?
On a turbo engine, a real and noticeable amount. On a naturally aspirated V6 or V8, mainly throttle response and shift quality rather than peak power.
Is a dyno tune worth the extra cost?
On a boosted or heavily modified build, yes, because it develops the calibration under controlled load. On a stock daily, a street tune is often enough.
Can you tune my diesel?
We can, carefully, because modern diesel tuning is limited by emissions controls. We tell you what is possible rather than promise a number.
How long does a dyno session take?
It depends on the build and how the engine responds, so we quote it as a range. A mild build is shorter than a boosted one that needs several revisions.
