Hi guys,

I have a Ecutek stage 1 tune by Perrin. The following are my mods:
-catback 2month ago
-Ecutek flash about 1 month ago or less.
I have P0134 and P0030 popped up 3 days ago. and still there now. took it to the dealer. and they said the Secondary O2 is not sending or picking up signal. I was pretty honest to them since I didnt care about warranty. I was told it has to be the Tuning by Perrin. because it happens after I flash my car. but was assured by Perrin that its definitely not the map because I flash to stock and clear codes. still there. Perrin was nice to send me another map which is the same map since i told the the subaru tech think you guys might have messed up. Codes change from P0134 and P0030 to P0031
My question is, would the tuning ever screw up your O2 sensor? By screwing up, I mean not functioning or incompatible with the tune on a programming base. I think im just going to replace my O2 sensor at this point and see if that goes away.

Thank you guys for reading!
