I had Brent (Brenspeed)dial in more delay on my front O2 sensor circuit. My code was mainly a nusience, I'd only get it every few weeks. After he dialed in the extra delay, I was getting that code almost every day. I went back to the first delay he set up & my almost daily code went away again. Seems some cars don't like the 'max' delay on those circuits.
I still get a P0153 on occasion, but I was able to almost eliminate it by just warming the engine up for 2-5min before I drive. I never had any issues with performance or drivability. Plugging in the tuner & clearing it once or twice a month is a trade off I'll live with for having the LT's & no cats. Love the sound & extra power I got with them.

I'd recommend you get with your tuner & have them dial back some of the max delay you already have programmed in.
