Most frequent questions and answers
Manufacturers generally sell one vehicle that covers various markets, with different tax and emissions regulations; different climates with extremes of heat, cold, humidity; different fuel quantities; different operating altitudes, etc. A manufacturer has to take all of these factors into consideration and make substantial compromises in the vehicles operation. We optimise the engine tuning and outputs.
Every Breslin Tuning Remap is guaranteed to ensure your complete peace of mind and continued service.
We offer a lifetime warranty against software faults. If the installation becomes faulty, we will re-install it free of charge. A professionally remap engine will not cause technical faults with a well serviced and maintained the engine.
A newton metre is a unit of torque (also called “moment”) in the SI system. The symbolic form is Nm or N•m. One newton metre, sometimes hyphenated newton-metre, is equal to the torque resulting from a force of one newton applied perpendicularly to a moment arm which is one metre long.
It is also used less commonly as a unit of work, or energy, in which case it is equivalent to the more common and standard SI unit of energy, the joule. In this very different usage the metre term represents the distance travelled or displacement in the direction of the force, and not the perpendicular distance from a fulcrum as it does when used to express torque. This usage is discouraged by the SI authority, since it can lead to confusion as to whether a given quantity expressed in newton-metres is a torque or a quantity of energy.
Brake horsepower (BHP) is the measure of an engine’s horsepower before the loss in power caused by the gearbox, alternator, differential, water pump, and other auxiliary components such as power steering pump, muffled exhaust system, etc. Brake refers to a device which was used to load an engine and hold it at a desired rotational speed. During testing, the output torque and rotational speed were measured to determine the brake horsepower. Horsepower was originally measured and calculated by use of the “indicator” (a James Watt invention of the late 18th century), and later by means of a De Prony brake connected to the engine’s output shaft.
More recently, an engine dynamometer is used instead of a De Prony brake. Although the output delivered to the driving wheels is less than that obtainable at the engine’s crankshaft, a chassis dynamometer gives an indication of an engine’s “real world” horsepower after losses in the drive train and gearbox. This gives a reasonably accurate indication of how a wheeled vehicle engine will perform once on the road.
If you want to tune your vehicle and still keep the vehicles safety and durability functions for the engine/transmission/ESP intact, the only way to tune a vehicle is to make changes in the existing control system of the engine. That is exactly what we offer with a Breslin remap. Our tuning process has total control over all parameters at any moment, and we don’t disturb the safety functions of the car by deceiving the system.
Apart from an obvious power, torque and fuel economy benefits you get the following advantages with a Breslin Tuning remap:
- The Breslin Tuning Remap is installed within the hour, normally without lifting the bonnet
- Nothing needs to be connected to the vehicle after tuning to get the benefits
- No loose boxes and wiring flexes in the engine compartment
- Torque comes soft and smooth
- Torque is adjusted/limited on lower gears (to avoid damage on the transmission)
- Boost pressure and air flow is optimised
- The original settings can be reinstalled if required
- On board computer shows correct fuel consumption
- Anti-skid program (ESP) function is fully retained
- Torque reduction when shifting gear (for comfort and durability) is retained
- Regeneration (emptying) of diesel particle filter (DPF) is retained optimal
- Correct calculation of exhaust temperature
- Correct calculation of service interval
- The diagnostic system is retained
- No enlarged NOx, HC, CO, CO2, Soot emissions compared with original when going for NCT and servicing
Our technicians link to the vehicles ECU or ‘brain’ with a laptop PC through the vehicles diagnostic socket and read the current engine management file which is then sent to our files office and custom optimised for you vehicle. The technician programs the new monster optimised file into your vehicle and you then have opportunity for yourself to experience the amazing results. On some vehicles it is not possible to carry-out this function be the diagnostic socket, so in this case the ECU is removed and either a chip change or boot loading function is carried out, direct into the ECU. The final effect is exactly the same, only the process is different. Depending on the vehicle, the remap normally takes less than 1 hour to complete.
Our Breslin Tuning re-mapping process enhances and optimises the power of the engine within safe limits, not beyond them. Extra power will also result in fewer gear changes, which might actually reduce overall wear. Manufacturers have to build in a tolerance for the parts in the engine, to manage the effect of wear and tear, production variations, and to ensure their warranty claims during their warranty period normally 3 years, are kept to a minimum.
Most race and rally engines are pushed for every last bhp, and thus they more common to fail, whilst normal car/van/lorry engines are limited back, well away from probability of multiple failures. Each individual engine is different as in how much it can be pushed in a remap, but a good remap from a quality tuner like monster will never get close the limits of component failure.
You will see that the top companies within the market place have all develop vehicle improvements to similar outputs. Beware of tuners who claim significantly more, it’s either lies hoping that the average customer wouldn’t be able to tell the difference, or the engine is being pushed too hard and will quickly become unreliable.
A full Breslin Tuning engine remap alters the fuel, boost and torque characteristics of the engine. By controlling the fuel pressure, injected fuel quantity, maximum permissible visible smoke limit, boost pressure from the turbocharger and the torque characteristic.
A Breslin Tuning remap offers a fully controllable change to the engine characteristics, whilst still operating with full engine feedback control and within all the pre-set engine sensor limits.
We are very confident that your Breslin Tuning Remap will both improve your driving experience and save you substantially on fuel. But, don’t take our word for it, try the upgrade for 30 days and if you are not delighted with the results, return to We advise that it is your responsibility to inform your insurance Company of any modification to your vehicle. We are finding that more and more insurance companies are not penalising their customers for saving fuel and recognise our economy upgrades, in particular with Breslin Tuning map. We can provide a certificate of conformity if required.our dealer and we will take it off with a full refund.
Torque is the twisting force created in an engine by rotating parts; horsepower is the measurement of how fast torque is being used. Horsepower and torque work hand-in-hand, as horsepower is calculated from torque.
For the average buyer, torque shouldn’t be a deciding factor unless you know you’ll be towing or hauling heavy loads. And that’s where high-torque vehicles will do well, driving while towing a trailer or maxing out cargo capacity. It will be easier to accelerate and sustain speed with a high-torque car in any situation, but especially with heavy loads.
High performance cars can also produce gobs of torque that greatly aid in acceleration. That feeling of your eyeballs being sucked into the back of your head in a fast car during heavy right-foot pounding is an example of excessive torque.
