Hi guys I am currently running Cobb OTS Stage 1 91oct... I have the Cobb stage 1 power pack and ATP down pipe. After hard acceleration code P061A comes on. I am pretty sure that this code is putting my car into limp home mode... I know that the code is for a PCM error. The code resets itself every time the car is turned off but comes back on after hard acceleration. I have called Cobb customer service and they informed me it could be the down pipe because stage 1 isn't designed for a cattless down pipe. I am also only pushing around 19.5psi max and boost usually holds around 18psi. I am going to tighten my clamps soon. Just wondering if you guys had any ideas of what is causing the code to come on.... I emailed Ian at Cobb today... Hopefully he will have some answers.
