Flashed my car using AP to stage 1 93 today. I have a CEL for P0031 Front oxygen (A/F) sensor heater circuit low input. I am only peaking at about 11psi. I feel like it should be higher. Especially with the stage 1 flash. I feel like it should be around 15-16. Would the oxygen sensor be causing the car to boost low? The car is completely stock except for a CAI that the previous owner had put on there. Putting on the stock intake by the end of next week waiting for a few more parts to come in. The car has always been boosting low, it's just now that I realized it when I plugged in the Accessport to read the boost as well as my boost guage both confirm that I am peaking around 10???? What the heck
Any input would be appreciated! Thanks!
