02 sensors keep getting burned c6 ls2
Ive had my c6 for almost a year now and it keeps frying my o2 sensors
I bought it back in march 2023 stock besides an intake and a axleback, within 3 weeks it burned the passanger o2 sensor. I ended up getting it built after taking it to the shop (cam and headers) car ran perfectly fine for about a month and a half which it then burned the sensors, took it to the shop and they installed spacers, changed the wiring etc. 3 weeks later they got burned again, again back to the shop replaced everything once again (thankfully free due to the sensors being under warranty). 2 weeks later all sensors burned again. Same process again back to shop replacing everything (free of charge once again) then a couple days after the sensors got burned again. The shop is now refusing to replace them and needs me to go to a chevy dealer (completely understandable for the amount of effort they've put) diagnostics on the eletrical
I am running texas speed headers with denso o2 sensors
tsp 233/239 cam
tuned after the build
Any idea what could be causing this? Was told it was most likely a fuseblock or my pcm - no fuse was blown for the o2s
Edit: the codes it's throwing is P0030, 0050, 0053, p0059

sounds like some issues with wiring if they were replaced with OEM sensors. Or, a bad tune, or injesting oil? My C6 afterfires a lot and my primary O2s have yet to die with all that abuse. Secondarys are removed.
