My LM1 only came with one 02, so the x-pipe like mentioned by JoeliusZ28 may be the best spot.

 

Didn't see that part of the post. If I weren't converting to bullets off the headers, I would run a wideband in my x pipe too. That way you can get both banks.

Let me know how the dyno and everything turns out. Glad it all went together. And if you're happy with the way it pulls to 4500, I can't imagine what you'll say when you pull it to 6800. That setup is probably just getting started by 4500.

 

Mike,

Congrats on the new setup and a successful start up. I'm looking forward
to checking it out at the next dyno tune day with Jeff. I'm taking the first
two weeks of January off to install the heads/intake/slp shortys and I'll also be
due for some dyno time, so count me in on a slot too.

I sent the OBD II PCM to Jeff for some additional CA smog tweaks and should
have it back today. Hopefully I'll pass and be good for another two years!

Keep us posted on your progress.
