It is also catless and straight piped (about 18 months ago)

But one month ago during some very rough and hard driving i suddenly felt the car shake.
I could also hear in the exhaust that there was a (what i tought) misfire.
I got it diagnosed the same day and there where no fault codes.

Changed al injectors coils and spark plugs, these are also gapped to 0.022.
Also lamba sensors are changed and the compression test was good.

So one month further still no real solution. just that we know it misfires on cilinder 2.
The software is the latest version and we also flashed it back to stock and it was the same.

Does anyone here have any tips? Would be apreciated.

thank you very much!
just curious how many HP you have on your tune?
