O2 sensor gave out after 7,500 miles!!
I noticed last night that I had a CEL come on outta nowhere! I called up my tech so we could go over the problem. Seems like my right side O2 sensor (right before the primary cat) gave out according to the diagnostics computer.
My tech had asked me what type of fuel I had been using, I told him 91 all the time. But occasionally I filled up 5 gallons of MS109 race gas. He said there was my problem right there. He claimed these O2 sensors are VERY sensitive. Finally went to Mercedes parts and picked up a O2 sensor, Installed it, cleared the codes, Problem solved.

If another O2 sensor goes out (I hope not) I'm getting BOSCH for sure.

This thing that I'm talking about will delete you 02's and relocate then. This is the best solution and 02's will never go bad and u can pass inspection.

Ya, its better with a tune but a tune alone is not gonna prevent your O2 sensors from going out because of high octane race fuel.
Yup.

02 sensor should be under warranty even with a tune and X pipe. Your tune has maps for increased octane and will advance timing thus netting you additional hp. But the octane maps only go so far and running anything over 94 octane is a waste. Thats why I mix 100 and 91.
