EGR removal on the L5P engine may enhance performance by reducing carbon buildup and improving throttle response, but it can lead to increased NOx emissions, potentially violating emission laws. Owners must weigh power gains against potential legal and environmental consequences. DPF removal boosts horsepower but drastically raises soot emissions, harming air quality and risking engine damage. Longevity may suffer, and legal repercussions are likely. Alternative strategies include aftermarket tuners
l5p delete, which optimize performance while preserving emissions systems, striking a balance between power and compliance.
