How does lambda-off affect fuel efficiency?<\/h3>\n\n<p>The ECU can no longer optimally adjust the air-fuel mixture, which may lead to slightly higher fuel consumption \u2013 especially during city driving.<\/p>\n\n<h3 class=\"wp-block-heading\">2. What are the risks of removing the catalytic converter?<\/h3>\n\n<p>\ud83d\udccc Higher exhaust temperatures can lead to valve and piston damage over time. Our tuning files optimize the ECU to minimize this risk.<\/p>\n\n<h3 class=\"wp-block-heading\">3. What happens to the sound after removing the catalytic converter?<\/h3>\n\n<p>\ud83d\udccc Louder, deeper &amp; more aggressive \u2013 ideal for sporty driving characteristics!<\/p>\n\n<h3 class=\"wp-block-heading\">4. What performance advantages does lambda &amp; cat deactivation offer?<\/h3>\n\n<p>\ud83d\udccc Improved throttle response, more power &amp; better sound \u2013 especially beneficial for turbocharged engines.<\/p>\n\n<h3 class=\"wp-block-heading\">5. Can lambda-off &amp; cat-off damage my turbo?<\/h3>\n\n<p>\ud83d\udccc No, not if properly tuned. Our ECU optimization takes boost pressure and exhaust temperatures into account.<\/p>\n\n<h3 class=\"wp-block-heading\">6. Is the removal of the catalytic converter legal?<\/h3>\n\n<p>\ud83d\udccc No, in most countries it&#8217;s only allowed for motorsport and off-road use. We offer tuning files exclusively for vehicles not approved for road use.<\/p>\n\n<h3 class=\"wp-block-heading\">7. Can I reverse lambda &amp; cat-off?<\/h3>\n\n<p>\ud83d\udccc Yes, the original file can be reflashed at any time.<\/p>\n\n<h3 class=\"wp-block-heading\">8. How can I recognize a faulty lambda sensor?<\/h3>\n\n<p>\ud83d\udccc Possible symptoms:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>Increased fuel consumption<\/li>\n\n\n\n<li>Jerking or rough engine running<\/li>\n\n\n\n<li>Check engine light (error codes like P0130, P0420)<\/li>\n<\/ul>\n\n<h3 class=\"wp-block-heading\">9.
