Hi sir,

My CTR FL5 replaced an RV6 catted exhaust and I flashed a pops n bangs tuning. When the P0139 code(O2 sensor circuit slow response) comes out the pops n bangs will not working. Wondering if I could block the DTC0139 code, will that effect AFR and damage the car?

The error code is for a reason - you should fix the cause. Pops and bangs switching off is to protect the engine.
