Here is a pic of the newer downpipe with the O2 extensions. Note that the third bung is not normally there. It was added for a wideband. What you are looking for is that your downpipe has those two extensions for the secondary O2 sensors:

What does this TSB actually do? Can I still get the TSB free even with the turbo? I'm not understanding what is going on here. Why are the codes coming up? What will the TSB do? Why will the TSB fix it? Why do I need to send in my ECU again?

Did you finally get these codes resolved??? I have the exact same 2 codes, P1274 and P1283 after my TN S/T kit install. I am racking my brain trying to find out how to fix it. I have the new version with the extensions on the downpipe and I still have these codes. Funny, TN said they haven't run into this problem before but clearly someone else has the exact same problem as me.

I had to dig this up.
I am unable to get an inspection because of these codes. Since they throw the CEL, I can't pass. So, I tried clearing them before going in, which didn't work. On the computer, it says my evap, and o2 are in a NOT READY status. Which means I cleared it before I went in for inspection. So I had to drive it around for the systems to be 'turned on'. After 45 miles or so, I went back in, the systems haven't turned back on, and he let me go withiout paying for the failure. Then after some more driving, the lights were thrown again. I will not be able to pass unless I remedy this.
What should I do with these damn codes? Really pissing me off...
PS I have the extension to the o2 sensors
