If you’re a truck owner or a mechanic, you may have heard of the concept of “stacking tuners.” This practice involves using multiple tuning devices to boost a truck’s performance and adjust engine parameters. However, as tempting as it may be, you should never stack tuners for many reasons.
Stacking tuners can sound good from the outside, but when you do this, you’re pushing the engine far beyond its factory-set limits. This can result in damage to critical engine components, such as pistons, valves, turbochargers, and even the engine block itself. The added stress on these parts will lead to premature wear and tear and costly repairs that you could have otherwise avoided. Any increased power you get will quickly turn into long-term damage and high repair expenses.
Another reason why you should never stack tuners is that it actually won’t lead to performance gains. This process doesn’t always work as intended. In fact, the tuners can sometimes conflict with each other, leading to erratic behavior and decreased performance. Instead of the smooth and powerful ride you’re hoping for, your truck will become problematic, filling your drives with engine misfires, poor throttle responses, and other performance problems.
In most states, it is illegal to tamper with emissions systems on vehicles. By stacking tuners, you are essentially disabling or altering the emission controls on your truck, which can lead to hefty fines and penalties if the authorities catch you. Beyond the legal ramifications, tampering with emissions controls can have a negative impact on the environment by increasing the harmful pollutants your vehicle emits.
Instead of risking your truck’s condition and warranty, there are safer and more effective options for achieving better performance. Entrusting the tuning to a reputable company, as well as upgrading other components like exhaust systems, air intakes, and intercoolers, can provide similar or even better results than tuner-stacking.
While it may be tempting to try and get the most out of your truck, you should never stack tuners. The potential consequences far outweigh any potential benefits.
