FAQs

What are the horsepower and torque ratings of the 6.4 Powerstroke engine?

While all vehicles have to strictly maintain the engine standards and stay within the emission norms, the Ford with its excellence was able to generate engine power as high as 350 HP and a torque of 650 lb-ft with the 6.4 Powerstroke engine.

Can a tuner be used for all kinds of vehicles?

The buyer has to be very specific about the tuner they purchase mainly to ensure that the specifications of the tuner are in line with the engine specifications. Most of the tuners are manufactured for left-hand drives. So please ensure that the tuner can be used for right-hand drives or imported vehicles if you own one.
Some tuners specifically mention being designed only for racing vehicles. In this case, also, it is important to understand that the specifications are read carefully before making the purchase.

Will tuning void my vehicle’s warranty?

Most of the tuners on the market have support for restoring the vehicle to stock settings. This can be done before the car is sent to the dealership for any service. In any case, it is a very tedious process to check whether the car has been tuned by checking the PCM. Also, the majority of the tuners compliant with the emission regulations do not tamper with the emission system of the vehicle and do not tune it to the very edge. Therefore, it should not be a problem in most cases.

Will the tuner lock the tune on my vehicle?

In some cases, the custom tune dealer has the ability to lock the tune on the engine if that is a specified policy of the tuner or the tune seller. In this case, you are forced to stick with that tune or tuner, and the only way to change is to replace the PCM. PCM replacement is a very expensive affair, and therefore, be sure to understand the terms of tuning and usage before making a commitment to any one brand.

Does tuning my vehicle for better performance increase fuel consumption?

Yes, since you want to optimize the amount of power delivered by the vehicle, you will probably be disabling the active fuel management module of the engine. This will allow unrestricted flow and greater speeds. However, this also means that the fuel consumption will be higher than usual. It’s a tradeoff between speed and fuel consumption.

Summary

Tuning of vehicles is one of the best and the most economical aftermarket solutions to improving the performance of the vehicle.

While there are professional racers who have the backing of bigger financial resources at hand to tweak the vehicle and get the most out of it, tuning is the go-to solution for someone who does not want to pop the hood and make major structural changes.

The 6.4 Powerstroke engine is one of the Ford heavyweights that already delivers a power-packed performance before tuning.

Tuning this beast will surely unleash the maximum power one can get out of Ford engines and make it one of the best choices for off-roading and towing needs.
