FAQ

Q. Is premium fuel a requirement?
A. NO. Because we custom tailor each program to our to our customer preferences,premium fuel is only required when the programming requires he use of such.

Q. What are typical horsepower gains?
A. 15-30% horsepower and torque is the normal expected improvements for gasoline.
Diesel engines can be 50% higher

Q. Will my engine run hotter with a performance tune?
A. NO. Engines will actually run cooler when properly optimized.

Standard with all performance tunes

Complete reflash of the PCM to your VIN, with all factory updates.
Dyno developed performance tune optimized for your exact engine and transmission combination.
Raised and optimized shift points.
Firm, but not harsh, shifts.
Some of the more common modifications to ask for.
Raising the top speed limiter to any speed you specify.
Specifying the exact shift points you want in every gear.
Firmer (or softer) shifts.
Specific tuning for your modifications, like larger than stock tires, gear ratio change,
supercharger, turbo, headers, cam change, higher stall converter, engine modifications, Air intake, Exhaust etc.
E/P tuning with 3DMapping for economy
The Guarantee
We will get your tune right, or will re-tune it at our expense until it is!
Lifetime warranty (no cost or fees, even if the dealer re-flashes it!)
Lifetime updates for all future mods Can't beat that!!!

All re tunes for any modification are Free

All our Performance Tunes will be re calibrated for any muffler or motor modifications and tire size for life.   Eliminating those annoying engine lights due to
Exhaust or Engine Performance modifications.   No more worries about flipping engines and tranny's
on your computerizes car or truck l can make any combination work,

One of the best ways to increase fuel economy is through efficiency . A combustion engine is an Air pump the less it has to work to move the air the more efficient
it will be.
Effectively using less fuel and increasing milage . All claims on this page are based on our driving styles to achieve the greatest milage for a given vehicle . Yours
may vary.

Fuel mileage gains are one of the main reasons for consideration of getting a reprogrammed ECU. Because we carefully remap the spark curve with a remapped
ECU, we in effect are increasing
cylinder pressure without adding fuel. Increased cylinder pressure translates into more usable torque and power to maintain the power required for 'rolling
resistance' of the vehicle down the road.

What is MGS Custom Tuning all about?
MGS offers customization at a level far surpassing off-the-shelf programmers. MGS offers a number of programming options, from an 87-93 dual
octane tune providing modest HP and torque gains up through a "hot" 93 octane tune that will blow away any other programmer's so-called "hot"
tune. While many handheld programmers claim performance gains, what they fail to tell you is that most of those gains are only available at the top
end of your RPM range. Programming will give you both HP and torque gains across the entire RPM range of your vehicle.

Each tune is customized for your vehicle based upon the VIN and engine of your vehicle. MGS first reflashes and updates the PCM with the latest
program available from GM & Ford for your vehicle and specifically for your exact vehicle Identification number, then modifies that program based
upon the parameters you specify

How the process works!
When you order a custom programmed from , it is programmed for your VIN and engine. The dealer cannot tell any custom programming has been
done. It looks all stock to them, we flash all the latest GM & Ford updates into it for your VIN#, so the dealer will see it is completely up to date and
not have to reflash anything. If by chance GM had an update in the future and the dealer reflashed the computer, just call us and we will custom
programmed , no charge for life, . Also, if you ever make any changes to your truck in the future, like even larger tires, different gears,
supercharger or whatever. We will custom programmed your vehicle .

Performance Tuning Options
Octane level. Performance tunes are now available with these octane choices:
In all our tunes, using higher octane will increase power and usually the gas mileage too!
The dual octane tuning, race mode Tow/haul and E/P 3Dmapping

1) Dual 87-91 Octane tune -- automatically adjusts for octane.. With excellent performance and gas savings

2) Dual 89-93 Octane tune -- automatically adjusts for octane.
More performance than the
87-91 tune, but requires using 89 minimum octane.(These dual octane tunes are recommended
for all dual purpose (work/play) trucks.

3) 91 Octane HOT tune -- much more aggressive than the 87-91 dual octane tune. 91 Octane minimum recommend

4) 93 Octane HOT tune -- much more aggressive than the 89-93 dual octane tune. 93 Octane is recommended
(Recommended for performance trucks. Limited heavy towing or hauling for both these Hot tunes!

5) Dual 89-91 Octane Dual HOT tune...The most aggressive and hottest tune available for 91 octane limited area’s! Eliminates pinging issues with
some engines running 91 octane by automatically adjusting to 89 octane level tune if pinging is detected. 91 Octane is recommended. Suitable for
areas where only 91 octane is available, and occasionally 89 octane. (Recommended for performance trucks. Limited heavy towing or hauling!)

6) Dual 91-93 Octane Dual HOT tune...the most aggressive and hottest tune available! Eliminates pinging issues with some engines running 93
octane by automatically adjusting to a 91 octane level tune if pinging is detected. 93 Octane is recommended. Suitable for areas where 93 octane is
available, and occasionally 91 octane. (Recommended for performance trucks. Limited heavy towing or hauling!)

40HP-200+**HP Computer upgrades--no add-on box--no warranty hassles.
The programming is in the truck computer.

Limit speed for Fleet accounts ! Reduce liability--increase longevity--good mileage gains.

** Race programming--suggest shift kit/trans rebuild above 130HP
New modification -- Now dyno'd 245HP and 515 ft/lbs above stock
with very little smoke opacity in comparison to other tuners. (549HP--1039ftlbs at wheels--PCM only)

The new 87/91, 89/93, 89/91 and 91/93 dual octane tunes will be able to run with the lower octane in MOST conditions with good performance, or
with the higher octane or anything in between when even more performance is wanted. The dual octane tunes are capable of tuning themselves
automatically for a higher octane, and retuning again automatically again when a lower octane is used. The factory tune will only advance the
timing to the limits set in the original spark tables. Filling the gas tank with at least 5 gallons of gas will trigger the automatic octane detection and
re-tuning feature.
