Hi folks,
I got the 130i tune on my 125i done by ptorque.
Anyone knows if the post cat O2 sensors are disabled or if they switch on if I decat my exhaust manifold due to the tune?

Thanks in advance :)

I think you will get lights unless you can get them mapped out but it's a closed loop so the secondary sensor checks the first one is working within range

So can i just make an adapter to increase the distance of the sensor from the cats?

Just get them coded out or get a emulator of some sort to connect to the cat wiring

Meant can you feel the difference with the decat. Is night and day difference or suttle
