What is the Nitro OBD2 Best For?

Nitro OBD2, as we mentioned earlier in this review, is known as an onboard diagnostics system. It is capable of managing several aspects of your vehicle’s engine and makes your driving experience much better and smoother. It has become popular amongst users as vehicles are now largely equipped with computerized systems, also known as ECU (Engine Control Unit).

Better Fuel Economy

The Nitro OBD II is capable of making your vehicle more fuel-efficient. This means that it gives you more mileage with a considerably less amount of fuel. This is really important, especially in this day and age, where carbon emissions and fossil fuels are alarming issues. To make sure your car is eco-friendly, you must make sure that it does not create excess emissions, and the Nitro OBD 2 is here to help with that. In addition to that, a fuel efficient car also means that you will not have to spend a lot of money on re-fuelling. This will help you save up that cost and utilize the money in a different way. Also, you will not have to worry about re-fuelling so often. You can enjoy your journey without any extra stops.

Increase Engine Power

Engine power, also known as horsepower, usually expressed in the unit kilowatts or horsepower, refers to the amount of power the engine of your vehicle is capable of putting out. The engine power can depend on a lot of different things, such as the size and the design of the engine. However, performance chips like the ones discussed in this review can help unlock the hidden engine power of your car or truck. It can increase the engine power by up to 35% so that you can experience the full potential of your vehicle.

Increase Engine Torque

In the simplest terms, engine torque can be referred to as the “turning force” or the “twisting force.” Torque is really important for vehicles, as it is needed to move the vehicle from a standstill, and is also needed when the vehicle has to climb a slope. Where the horsepower of a vehicle will refer to its top speed, the torque will refer to its acceleration or pickup. Performance chips can come in handy here as well, as they can aid in increasing the engine torque by up to 25%.

What Do I Need to Know Before Buying?

There are a few factors that you need to keep in mind before you decide to invest in a Nitro OBD2 Performance Chip and plug it into your vehicle. It is best to be aware of these facts before you make any sort of changes to your vehicle or its engine. Let’s shed some light on what these things are.


While performance chips are a great way to unlock the full potential of your vehicle, it is important to know that if you decide to use a performance chip, you will void your car of its warranty. In other words, should your vehicle face any sort of damage, the company will not be responsible and will certainly not cover the cost for any kind of damage that your vehicle may have the misfortune of facing. This is quite the price to pay for unlocking the potential of your car or truck. However, customers are assured by the makers of these performance chips that absolutely no harm will come to the vehicle’s engine, and the chips are completely safe to use. They do not make any changes to the ECU system either.

Changes Are Not Permanent

Another essential thing to keep in mind with these performance chips is that the changes they make to the fuel economy, engine power or engine torque are by no means permanent. They will last as long as the chip is plugged into the OBD II port of your vehicle. The minute you take the chip out, your vehicle will go back to the way it was. A more permanent solution would be remapping or ECU tuning, but that is a much more expensive option, and it is not always reliable, as it can put a strain on the engine.

Vehicle Compatibility

Before you decide on which performance chip to buy for your car, be sure to check that it is compatible with your vehicle. As mentioned in this review, compatibility is not that big of an issue, however, that does not mean it should be overlooked. Most chips are compatible with vehicles made in 1996 and onward, but make sure that your vehicle is OBD II-compatible and that it was manufactured in the right years. Otherwise, you will end up with a fancy-looking device which is of no use to you at all.

Bottom Line

Both the products reviewed in this guide have their pros and cons, but it is clear to see that the pros easily outweigh the cons. Performance chips are a quick and easy way to increase the performance of your vehicle so that you can enjoy driving it at its full potential. These chips, although small, are capable of amazing things, and the best part is that they are so budget-friendly, it is almost unbelievable.

Furthermore, performance chips are definitely a better option than remapping your engine, which puts a strain on the engine, and may cause damage. Meanwhile, performance chips do not cause any type of damage to your engine. You can easily plug them in, and when not needed, you can just unplug them. Apart from that, they make your vehicle eco-friendly, which is much needed nowadays as it is better for the planet and everything that lives on it.
