I am getting the check engine light with code B14A1 when I drive hard with the AC on. Anybody getting this? The check engine light goes away but comes back if I drive it hard with the AC on. Just started getting this in the last month. I have a ECUTEK tune by dynotronics.

My code went away once the E85 was gone and I flashed to the Stage 1 v2.0 OFT 93 tune. The P0463 is clearly related to E85 is most documented cases which is disappointing.

Just got this code wednesday when I was heading to lunch. I only have 5400 miles, I guess it is related to bad gas.

Just threw the P0463 code. Running on 91 gas and tuned with OFT 91 octane stg1 map. Any ideasa? Is it serious? Always refilling on Cheveron, about 27k miles, gas light is on when the code went off.

does not seem to be tune related suspect the P0463 code is due to problem with fuel level sender in tank or bad connection or wiring to fuel level sender. Never had that code myself.

I've got the p013f after installing my wideband in the secondary o2 slot. I turned all the codes off that I thought related to the secondary when this one showed up after a few cycles. Is anyone else with this code tuned?

No, this light still comes on from time to time when my fuel gets low. Nothing seems wrong with the fuel system, and car is operating normally as it always has.
