Catless UEL and OFT Stage 2+..... use o2 spacer?
 

I have a Megan racing catless uel and tuned with stage 2+ OFT.

The Megan came with an angled o2 spacer so I installed it on the rear o2, but it seems maybe I shouldn’t have since I have the tune?

Should I remove the right angle o2 spacer with my setup, and just install the rear o2 sensor without it?

Up to you. Removing the Rear O2 sensor would probably help preserve it, but as far as the function of the car, the tune probably doesn't even use the readout on the sensor for anything.

I took mine out but it doesn't hurt to keep it in. It actually makes your o2 wiring a little longer. Mine is a tight fit without the angeled spacer.
