Whipple P219B

[135Hoser]

Got a P219B code on my whipple.

Apparently whipple has an updated calibration to address this, but they chose not to notify me, neither did FP or the dealer that installed it that it was available.

Kinda annoyed there's not just been multiple tune revisions, but that I don't get any heads up about them despite having contacted them previously about getting the tune updated.

Car was adding 13.3% fuel on one bank, 10% on another at cruise for long term fuel trims.

Pretty sure it's time for the cats to be removed, and hopefully there was no damage done to the motor by the ford performance tune that gets worse once the cats and warranty are gone.

No matter whats wrong, you need to remove the cats.

Are you using an octane booster? If so, I would replace the front widebands and also remove the cats. Then you'll likely be fine. Dont bother yourself with LTFTs. They can get skewed and the shorties will offset them in real time. I see it all the time. Once you see them all together, they even out.
