I am going to be running the GM reflash on my turbo setup and want to know if I need to have my primary O2 sensor in, and if so should it be back in the mani?

Also do I need a piece of flex pipe in my downpipe if I have both motor mounts? I noticed there was not any flex pipe on the stock exhaust.

Yes, you will need to keep your primary o2 there. the car will not run right without it. I personally don't have a flex pipe in my exhaust, but it's probably not a bad idea.

So do I need to put the primary O2 back into the log mani, or can I put it in the DP right after the turbo???
