Now i'm on my 3rd revised tune from Brenspeed. The first tune did not comp for headers, the second did, but they turned the rear 02's on by mistake (catless), and now that I have revised turning the rear 02's back off I am now getting the P1053 back on. What I want to do, is go back to the previous tune that did not trigger the P1053, and run MIL eliminators to trick the rear 02's, question is do they work on S197's? I see AM has them, but only for 99-04. Any know if they will work?
