Any Whippled Mustangs have hidden trouble codes?

Pulled DTCs in Forscan after 2 autocross events this past weekend and have a P219B. Might be my stock cats going, IDK...
Anyone have experience with this code? Trying to find the easiest diagnostic path.

Time for long tube headers, no cats, and a custom tune to extract another 50-75 horsepower!

I recall in one of Misha Charoudin's videos in a Dark Horse around the Nurburging Nordschleife that he was having fueling problems. He didn't report on any codes, just he could feel the lack of fuel and speculated it was g-force induced.

Curious about the outcome because I have a Whipple too. I know the Tomahawk tool used for loading the Whipple tune can read DTC's (I assume all). I checked for non displayed DTC's after reading your thread and the Tomahawk tool showed no DTC's present.

Again, curious what you found out. I'm guessing nothing major. Best of luck sorting this out! Would you mind seeing if the Tomahawk tool picks up your DTC?

The fuel trims are not way out of whack, but I'd be doing a quick check of the vacuum hoses for a leak, as in open the hood and listen. Check to see if the hoses you can see and get to are on snug.

The long term trims are positive, meaning it is adding fuel and you really want those to be closer to zero than they are, anything over 5% is normally cause for concern in a NA car and I know you are boosted and the freeze data says you were under boost when it captured the data but it looks like you might be getting air somewhere, at the engine load it is showing I don't think it is starving for fuel.

You may have to get a good scanner hooked up and read the data as you drive it.

It may just be a glitch, I swear sometimes cars toss codes just to watch us chase our tails.

but again, the long term trims are not where I would want them

Code went away and never triggered a dash light. Another autocross this weekend... we'll see if it returns.
