Could be a bad or damaged wide band O2 sensor or you could have an issue where the engine is running lean. We need a lot more information inorder to help.

Without getting into a lecture (rant more likely) about this tune regardless of the DP configuration first we need to determine if the sensor is damaged or if you are experiencing a fueling issue.

Please give us more information about your configuration. Mods, tune, etc.. there's not enough information to help.

The Wideband O2 is a critical component and you should consider fixing this before driving around to prevent damaging the engine.

all i鈥檓 running right now is a blow off valve, cobb intake, res and muffler delete. I ran the crackle pop tune for one week and that was 2 weeks ago. I took off the tune because i don鈥檛 have a catless downpipe
