Custom Dyno Tuning Toyota Landcruiser 300 Series

Your TOYOTA LANDCRUISER 300 SERIES can become significantly slower when towing, especially when your air conditioning and other accessory systems require power to run, and the engine provides that power.

Many drivers feel frustrated while driving, making simple overtaking a big problem. Applying full-throttle is a natural reaction when they think their TOYOTA LANDCRUISER 300 SERIES are incapable of performing as they expect.

This is because a diesel engine is meant to deliver a strong "torque" delivery and towing force at middle ranges of engine speed (2000-4000rpm). As a result, the car cannot complete an overtake even at full throttle if driving on a gently sloping road with a medium load onboard.

This results in potentially unsafe driving conditions and higher fuel consumption.

A Stage 1 tuning package is a popular enhancement choice among diesel car enthusiasts seeking to boost their vehicle’s performance without compromising reliability or drivability.

The typical Stage 1 Diesel tuning package for a diesel car involves adjustments to the engine’s software or ECU (Engine Control Unit) to optimize its performance. This leads to a notable increase in power and torque, enhanced throttle response, and an overall improved driving experience.

These modifications contribute to heightened engine intake and exhaust flow, resulting in improved breathing and enhanced power delivery.

It’s crucial to recognize that any alterations to your diesel vehicle’s engine could potentially impact its reliability, emissions, and warranty. Consequently, it is advisable to select a reputable tuning company with expertise in diesel vehicles, capable of offering a customized tuning package tailored to your specific requirements and objectives.

In summary, a Stage 1 tuning package for diesel cars can be an excellent means to elevate performance and driving enjoyment. However, it is essential to carefully weigh the potential risks and benefits before proceeding with any modifications to your vehicle.

Stage 2 Package Inclusions:

A Stage 2 Diesel tuning package typically involves more comprehensive modifications to the engine and other performance components compared to a Stage 1 upgrade. This can encompass additional enhancements to the intake and exhaust systems, as well as upgrades to the intercooler.

Opting for a Stage 2 tuning package brings a notable increase in power and torque output when compared to a Stage 1 package. 

It’s crucial to bear in mind that a Stage 2 tuning package can have a substantial impact on your vehicle’s emissions. Thus, selecting a reputable and experienced tuning company is essential to receive a custom-tailored package that aligns with your specific goals and requirements.

If you’re contemplating a Stage 2 tuning package, a thorough consultation with the tuning company is recommended to discuss potential risks and benefits, as well as any necessary modifications for optimal performance and reliability.

Additionally, upgraded drivetrain and suspension components are often necessary to handle the increased power output.

Opting for a Stage 3 tuning package brings a significant boost in power and torque compared to Stage 1 or Stage 2 upgrades. However, it’s important to note that this level of modification is not recommended for daily drivers, as it may lead to reduced reliability, increased emissions, and decreased drivability in traffic.

It’s crucial to be aware that a Stage 3 tuning package may potentially void the factory warranty and could be deemed illegal in certain jurisdictions. Hence, selecting a reputable and experienced tuning company becomes essential to receive a customized package meeting specific goals and requirements, all while ensuring optimal performance and reliability.
