Discussion and questions related to the course Practical Reflash Tuning
Hi. I’m having this exact problem on my 2005 Audi A4 2.0t. Ever since I deleted my cat it has been throwing o2 sensor codes and misfire codes. I have upgraded plugs and could packs. Also upgraded intake and a full exhaust. I also have Maestro 7 editing software. I just need to know how to tune it. Thank you!
