Car running too rich

[Corroeric]

I have a 2021 Mustang GT with a cobra jet manifold, steeda closed box intake, and headers. I'm currently on 91 Pump tune and I'm having issues with the car running too rich. I got codes P0175, P0172, and P2BF1 and I was told the car is running 30% lean. I was told it's because of the steeda intake and I don't see how that could be the cause. Any help or recommendations.

It's possibly in the tune......

Tune or a vacuum leak.

More likely the tune due to the intake than the intake itself. Was the correct maf data provided? All mods provided when they built the tune? What tuner being used and what was their feedback on it?

If it's a no tune required intake then it's a vacuum leak. What intake is it.

I got a revision from lund and it’s still doing the same thing.

Yes I dialed the car a couple months ago when I added everything and it was running strong and out of nowhere it’s doing all the stuff I mentioned.

It’s the steeda closed air box cai

if you start having problems now after it was fine, you should check for vacuum leaks.

Will start with that thanks!

Did you ever get a solution? I just popped a P2BF0 and that’s it
