LAP3 meth issues

[Swatteam185]

I've had a LAP3 piggyback tuner for most of the life of my stinger. When it's not spraying meth it's wonderful!

A couple months ago I swapped out my primary downpipes (and removed the turbos to drill out and replace the studs lol). Without giving it much thought I put the o2 sensors back in the bungs without spacers and now I've got myself a nice CEL for cat efficiency. The car drives differently with this cel on and I've basically got to give it full throttle for it to do anything at all.

When I run meth on this setup and try for a pull, the entire car shudders and starts misfiring like crazy. I've got an AEM failsafe gauge that's telling me it is spraying the right amount of meth based off mapping from the time before my cel.

I'm curious to know if this is caused by the cel throwing the car off or if it's a separate issue. When the weather gets better I'm going to get around to putting spacers into the o2 bungs so I can get rid of the cel. I've also been looking at a tork ECU tune and AEM meth control aswell - being certain that these things would allow me much greater control over what's happening to my car. It feels like the LAP3 meth system is kind of wet and forget, I have no clue what's going on inside the software.

Are you going into Limp Mode with the CEL? You should be able to clear the codes with the Lap3 - Can you do that? What version of Lap3 do you have?

Not LIMP mode like a normal car. It drives but it lacks an edge, it's not aggressive.
I clear the codes, but it's never permanent. When I reset the battery the cel disappears for a few miles then comes back on.
I have UncleChip V1.39

From my understanding, the UncleChip is a discontinued product that Lap3 USA does not support. I do not know much about UncleChip so I am afraid I cannot help much there like I hoped I could. I run the Lap3 Protuner 2.5 with Meth and have so for about a year now (about 6 months with Meth) with no issues at all.
