Frequently Asked Questions
Do diesel power chips really work?
Yes, diesel power chips can increase horsepower and torque by modifying engine control parameters such as fuel delivery and boost pressure. However, actual gains vary by vehicle and chip quality. Our research shows that reputable chips from Edge, Bully Dog, and Superchips deliver noticeable improvements, while budget chips may offer more modest results. It is important to have realistic expectations and understand that extreme gains can stress engine components.
Will a power chip void my vehicle warranty?
Installing a power chip may void your vehicle’s warranty if it causes damage or if the manufacturer can prove the chip led to a failure. The Magnusson-Moss Warranty Act in the US requires that the warranty denial be due to the aftermarket part. To minimize risk, choose chips with safe tuning parameters and consider removing the chip before dealer visits. Some chips offer a ‘stock’ mode that returns the ECU to factory settings.
Are diesel power chips safe for my engine?
Safety depends on the chip’s tuning and how it is used. Chips that increase fuel and boost within safe limits, and include monitoring for EGT and boost, are generally safe when used responsibly. Aggressive chips without monitoring can lead to excessive exhaust gas temperatures, which may damage pistons, heads, or turbochargers. Always follow the manufacturer’s guidelines and avoid sustained high-power operation without supporting upgrades.
