The higher pressures wear out the injectors faster — this is a common-sense fact. Secondly, will a programmer hurt my truck? Tuners do not damage transmissions, drivers do.
Drivers should practice caution and often times reprogram their truck to a lower HP tune depending on the conditions they will be driving in. For example, stock trucks should not be towing on a HP tune. Diesel tuners , including chips, modules, and programmers, all work by modifying the stock engine parameters like injector pulse width, boost pressure, and fuel rail pressure, raising the performance of your truck well beyond its factory tune.
A performance chip does not cause damage to your engine or transmission as it increases the horsepower and torque output. The short answer is that diesel chip tuning is generally very safe but with one proviso. Unlike with petrol engine where adding more fuel cools down exhaust gas temperatures, adding excess diesel has the opposite effect and this is why you do not want to use a chip that causes excess black smoke.
Can you chip a diesel engine? There is no doubt that performance chips on diesel engines can negatively affect how long a diesel engine lasts, but on the other hand, there are millions of diesel engines in operation that have not blown up within ten minutes of having had chips fitted. Is it worth Remapping a diesel engine? It is not worth remapping a naturally aspirated non turbo diesel engine. The power gains are not worth the expense. Connect with us.

These devices operate by monitoring turbo boost pressure, engine RPMs, coolant temperature, airflow, fuel rail pressure and other operating considerations such as trailer load and then balancing these parameters by changing the electronic tuning characteristics of the engine management system to yield optimized performance.
Do they increase miles-per-gallon? Some of the latest gauge tuners even have a built-in driving coach that offers tips that help develop positive driving habits to improve fuel economy. Do they improve speed and acceleration?
Programmers extract this power by adjusting the operating conditions of the engine toward increased performance. Can they monitor engine function and prevent damage? Modern gauge tuners also provide a set of diagnostic functions that enhance safety.
Are they hard to install? Do they cost a lot? Watch a webinar for free on-demand! Most tuners have tunes that are made to work with completely stock vehicles. These tunes are generally rated at HP and under.
You might notice that some tuners come with tunes above HP. If you tune a stock truck to a setting above HP you will most likely not have enough fuel to supply the demand that this particular tune. A simple add-on, and one of the first upgrades you should install, is an upgraded lift pump filtration system.
These systems supply more fuel to your engine allowing you to actually achieve the HP rating that the tunes claim. Running a tune of this caliber on a stock or non-performance clutch can cause it to slip, and eventually cause the clutch to fail, leaving the driver stranded on the side of the road. We recommend upgrading to a performance clutch such as a South Bend or Valair Clutch system.
These upgradse are not necessary unless you plan to be over aprox. A stock truck is more than capable of handling HP and under tunes, as long as the truck is not towing excessively heavy loads. Tuners will only work on one truck at a time. Some tuners do allow you switch between trucks once the tuner has been completely removed from the vehicle. Some tuners however, have a feature known as vin locking. This means that when the tuner is installed onto a vehicle it registers and permanently mates with that particular truck.
The tuner can be completely removed from that truck, but it cannot be installed on another vehicle after that. In the performance industry the act of combining two tuners on one vehicle is known as Stacking.
So, opting to only upgrade things like the intake and exhaust, may meet their desires without unnecessary anxiety. We mentioned that diesel engines are very reactive to upgrades.
Take, for example, the time that PowerDrivenDiesel, an online retailer of diesel performance and replacement parts, paired up with Diesel Tech Magazine to work on a completely stock Dodge 12v Cummins. The dyno test in the video shows that they were able to double the horsepower and nearly triple the torque. They modified the fuel system and injection timing.
Installation is more complicated than the average tuner, but AFC Live allows users to dial in the total amount of fuel available for various uses like street driving, towing , drag racing, etc. Simply adding in a performance tune without addressing how the engine will sustain those power gains, may land you in a position like the truck owner in the DEBOSS video.
Additionally, there is no one-size-fits-all programmer.
