I will clear the codes today and monitor it. I have the feeling it's the JB4 pushing the fuel and idles up that's causing this.
What map are you running? I'm on map 3 with titan downpipe/fabspeed cat and no codes.

Yeah, sounds like something else. I'm on 93 octane with DP and no codes. Any other mods or changes to car?

Only k&n drop in filter with gray foam removed.
Ok, similiar here - I'm running the AFE dry filter with carbon foam removed.

You didn't happen to oil or clean the K&N did you? I've heard TONS of stories of K&N's dumping oil on the MAF and causing issues.

Nope. I just drop the filter in. There wasn't enough oil on it to drip anything.

You have the Fabspeed extender and no CEL? I got downpipe installed yesterday and now have a CEL. Is it possible to switch out an extender without having to dropping take out downpipe? From the bottom perhaps?

Shouldn’t you run map 4 with downpipe? I’ll try going back to map 3 sea what happens.

I upgraded the JB4 firmware to V14. It says map 4 is for BEF setup.

I have never had patience....

Got home from work, my “race ramps” won’t arrive til tomorrow, I thought, what the hell, let’s give it a go and try the install with my 6” plastic ramps...

2.5 hours later, the DP is in....I know, I know, I am a little slow. However, doing the downpipe with your nose rubbing on the underbody of the car sucks. I had to do some magic just to pull the downpipe out as there wasn’t enough clearance between the ground and the car to remove it. Lol

I installed the fabspeed spacer. No codes, but all I have done is start the car to check for leaks. We got snow today, so I couldn’t drive it and I didn’t want wake the neighbors revving it.

One concern I have is the wires from the secondary cat are pretty close to the engine (due to the spacer)...when I first started the car, I smelt some melting....I think it was just the new pipe, but now I am paranoid and may go in and try to move the spacer further from the engine...

Running JB4 as well...map 1 for now.

Should I be worried about this wires location?

That spacer looks different than my Fabspeed spacer. When I ordered through Titan they didn’t specify which I would be getting. Maybe the other one would clear the CEL

Check you're jb4 install, that all cables are correctly installed, in my raptor, you will get some codes if you install the jb4 incorrectly....just sayin
Thanks U checked it again and cleared the code last night. Will monitor it and hopefully it doesn't come back again.

Looks the same as what I got from Titan. Yeah, the Fabspeed mini cat is large - there isn't much room. As long as the o2 cables aren't touching anything you should be fine.
