Adblue Delete kits are becoming increasingly popular among diesel car owners. While a Stage 2 tune offers performance enhancements, understanding the variations within AdBlue delete options is crucial. This article explores the differences between an AdBlue delete only and a full delete kit, including the implications for performance, labor, and emissions.
AdBlue Delete Only vs. Full Eco Kit
An AdBlue delete solely focuses on disabling the AdBlue system, typically through software modifications or a hardware emulator. This eliminates the need for AdBlue fluid refills and potentially prevents future system failures. However, the exhaust system remains untouched. Conversely, a full eco kit often encompasses AdBlue delete, Diesel Particulate Filter (DPF) delete, and Exhaust Gas Recirculation (EGR) delete. This comprehensive approach alters the exhaust flow and can lead to noticeable power gains due to reduced back pressure and increased oxygen in the cylinders.
A full eco kit often necessitates replacing various exhaust components. The DPF is removed, and depending on the kit, the EGR system may be bypassed or removed. This requires more extensive labor compared to a simple AdBlue delete, which primarily involves under-the-hood work.
Power Gains and Exhaust Modifications
While an AdBlue delete alone may offer negligible power gains, a full DPF, EGR, and AdBlue delete can significantly impact performance. Removing the DPF reduces exhaust restriction, allowing for freer flow and potentially increasing horsepower and torque. The increased oxygen in the cylinders, combined with the ability to inject more fuel, further contributes to power gains.
Resonator and High-Flow Cat Options
Resonators and high-flow catalytic converters play a vital role in exhaust sound management. A resonator helps to reduce droning and unwanted frequencies, contributing to a more refined exhaust note. A high-flow catalytic converter allows for increased exhaust flow while still reducing harmful emissions compared to a completely straight pipe. Choosing these options within a full eco kit helps maintain a less aggressive exhaust sound, preventing excessive loudness or raspiness.
Emissions Testing and Legality
It’s crucial to understand the legal implications of AdBlue and DPF deletes. Tampering with emissions systems is illegal in many jurisdictions and can result in fines or failed inspections. Vehicles with a full eco kit will likely not pass emissions tests due to the removal of the DPF. Always check local regulations before modifying your vehicle’s emissions system.
