Here's why you can't just "turn it up" and what's involved:
* Electronic Control Unit (ECU): The ECU manages fuel delivery, timing, and other critical engine parameters. Simply increasing fuel pressure without adjusting other parameters could severely damage the engine. The ECU's programming is complex and requires specialized tools and software to modify.
* Fuel Pump: The fuel pump's output is precisely controlled by the ECU. Attempts to mechanically increase fuel output will likely upset the ECU's calculations and lead to poor performance or damage.
* Injection System: The injectors themselves are carefully calibrated. Increasing fuel pressure beyond the design parameters can lead to excessive fuel spray, increased cylinder pressure, damaged injectors, and potential catastrophic engine failure.
* Increased Wear and Tear: Running a diesel engine with increased fuel delivery beyond its design specifications dramatically increases wear on the engine components, such as the connecting rods, pistons, and bearings. It drastically shortens the engine's lifespan.
* Emissions: Increasing fuel delivery will almost certainly increase emissions, potentially violating emission standards and regulations.
Instead of trying to "turn up the fuel," consider these safer and more effective options for increased performance:
* Performance Tuning: A professional tuner can modify the ECU's programming using specialized software to optimize fuel delivery and other engine parameters for improved power and efficiency while minimizing the risk of damage. This is the safest way to increase performance.
* Upgraded Turbocharger: A larger or more efficient turbocharger can provide a significant increase in power without the risks associated with altering the fuel system.
* Exhaust System Upgrades: A free-flowing exhaust system can improve performance by reducing back pressure.
In short: Modifying the fuel delivery on a 1995 Dodge diesel is extremely risky and should only be attempted by experienced mechanics with specialized tools and knowledge. Seeking professional help for performance upgrades is strongly recommended. Improper modifications could result in significant engine damage and costly repairs.
