Well damn. As you stated above a pro tune will probably be your best bet in resolving this issue. With the mods you've done (CTR Turbo/Downpipe) no telling what is not speaking/acting right. Good luck on getting it sorted and let us know how it was resolved.Ya I did. They told me to follow Honda service manual for diagnosis. Very disappointed with their response. It’s obviously the tune as a sensor can’t work for 14 days and then act up. Kinda tempted to change my car but I really like the car.
