How much is a custom dyno tune?

Typical cost for a dyno tune is between 350 and 750 USD.

How much does a dyno pull cost?

Typical cost for dyno time is 75 to 150 USD.

Does Dyno tuning make a difference?

Only if the vehicle is not properly dialed in.

What is a custom dyno tune?

Adjusting spark, fuel, cam timing, transmission settings amongst other controls the ecu is capable of controlling to properly calibrate a vehicle so it runs properly.

How long does a dyno tune last?

Until the engine is modified.

How much HP will a tune add?

As much power as it was lacking from running imporperly. Each vehicle will be different.

Is a dyno bad for your car?


Does a dyno hurt your car?


Is it safe to dyno a car?

Operating a vehicle on the dyno is typically safer as operations can be monitored closer. However airflow is reduced significantly so overheating can become a concern.

Is a dyno tune better?

A dyno is just a big ass torque wrench used to measure gains and losses after each adjustment. Its a good starting point but the best tuned vehicles are those that are dialed in at the track.

Can you tune without a dyno?

The track is the most common tuning grounds. But vehicles can be tuned on the streets as well by monitoring performance gains or losses after each adjustment.

What's better street tune or dyno tune?

The best option is for both.

What is a Stage 1 tune?

A bullshit designation that means absolutely nothing.

Can you dyno tune a stock ECU?

Most tuning shops will tune stock ecu's but first verify with your shop.

Can you Dyno an automatic car?

High horsepower automatics require a load bearing dyno.

What can I expect from a dyno tune?

A vehicle that runs properly.

What is the best Ford Tuner?

In short, there is no best! All tuning hardware does the same job, it replaces the current calibration on the ecu with its own.
As for software, they all do the same job, some software has access to more parameters than others and some software is easier to use, however, all tuning software is basically the same minus the support for your specific vehicle/ecu your tuning with/on.

Hope this clears up alot of confusion, there is no "best", just "most appropriate".

Who is the best Tuner?

Decipha is the best ford tuner hands down! I only kid. No tuner is any better than any other. The tuner's job is to get the most amount of torque out of an engine as safely possible. This is done by adjusting ignition timing (spark), air/fuel ratio, variable cam timing, transmission shifting and torque converter control, supercharger bypass and any other controls the ecu has the ability to control. The tuner themselves cannot get any more power out of an engine than the engine is capable of. So no tuner is better than any other tuner. However some tuners can be overly conservative and some can be overly aggressive with ignition timing which plays the largest role in power.

Your best tune will come from being completely honest with your tuner and giving him specifics on how the vehicle will actually be used. This will make the tuners job easier and you'll be happier with the results. Communication is key.

Can my tune cause a no start?

The EEC-IV and early EEC-V ecu's do not control the starter relay "solenoid", however if you have a 2003 - 2004 EEC-IV in a Maurauder, Crown Victoria, Grand Marquis and a few other explicit advanced control ford vehicles then YES, a faulty tune will prevent the starter relay from engaging.

Can you always tune for more power?

No, an engine is a compressor its simply an air pump, horsepower is directly related to the airflow the engine can move, in order to make more power the engine must move more air, this is a physical limitation that no amount of software or fingering of a tune can compensate for.

Can I use a 94-95 Mustang V6 ECU to swap into my 5.0 foxbody?

No, the v6 ecu's only have 6 injector outputs, you can use an 8 cylinder ecu in a 6 cylinder or 4 cylinder engine, but you cannot use a 4cyl or 6cyl ecu in an 8cyl.

Happy tooning.
