Off-road headers and O2 sensors

[Christang.GT]

Also, I am having an issue with the O2 sensor now, I think it is going out. Pulled the codes and sure enough open circuit on bank 2 sensor 1. But it’s making my car idle all wonky and furthermore now, it’s causing misfires and sputters all over the place I’m wondering has anyone had these issues with a dedicated flex fuel tune and a bad O2 sensor

Is that the crank relearn? I have a sct device, I haven’t tried that yet what is it?

With the ported 18/ NA cams combo and a dyno tune do you think I could hit 500 whp? I was looking into a ported CJ mani because I know for sure that would do it. But also I don’t know many good tuners in my area

Why go through all that effort and money for virtually no gain?

That N/A build is coming damn near a supercharger in cost with like 20% of the gains.

Throw a procharger on and enjoy doubling your stock horsepower without messing with any of the mods you already have besides a new tune and bigger injectors.

I daily the car and I don’t want to run into many other issues FI might bring (trans going out, snapped axles etc) I’m not saying I wouldn’t like to do that but I absolutely live NA builds and yeah I might not get the gains of FI but longevity sake I want to stay NA. When I say I daily it I daily it lol, it’s a 15 and I got 145k miles on it. Idk who else has higher but it’s up there and so far holding strong ofc I got more maintenance and issues because nothing is as good as stock but I want to push the limits of a coyote at 500whp, I want to see if it’s possible to get high high up there in miles. I’m locally hated for this btw, everyone says get a daily and take care of it which I do, it’s not dinged, scratched or anything. I did a compression test about two months ago and all solid numbers so I have no issues there. I just want to see how far it can go with “enough” power
