Ferrari Mailing List: NFC: Oxygen sensors?

[Tom Reynolds (kjtar]

Dear Listers,
        In my new to me '96 Chevrolet Camaro Z28 SS (modified by SLP 
Engineering as an option code on the original order form) I've been having a 
local Camaro/Firebird guru do a laptop tune on it.  We want to get a good 
baseline for further testing and future dyno. 
        He's said that it's his opinion that I should get two new pre-cat 
oxygen sensors.  He's also heard that those made by Bosch for the application 
are not recommended.  Anyone have opinions on what I should be looking for?  He 
says that AC/Delco is the OEM replacement, but I'm not sure about that.  I have 
looked up online, but (of course) am confused by application choices. I've 
posted on chirpthird's SS forum, but so far no response, and the Z28.com and 
LT1 section of the LS1 forum keeps kicking me off... 
Help?
Thanks very much,
Tom Reynolds
