i have an 09 ss/tc and just bought a wideband, everything looks good just unsure of which wire to splice into. any one no which wire off the o2 is the sender wire? also ive noticed that our cars sound like a timebomb, i figured it had something to do with the injectors or the direct injection set up but wasnt sure. i went to a local gm garage and ask some guy that was sapposed to b the lead tech, he didnt hardly no anything. he said it was the turbo. lmao! but he did say something about a hose that u could take off to make "max boost". idk wat he was talkin about but it made me curious. has anyone else heard of this? also how much boost can our turbos push safely and safely w/o a tune.. thanks for all input.

 

Return your wideband and get an interceptor lol since our cars come with wideband o2 sensors and the ticking is the high pressure fuel pump. Ticking is normal and the tech is a ******* idiot

 

That tech you talked to sounds like a idiot. You will need a tune to make more than stock HP because even with a MBC the ECM will limit the air it is receiving because it is exceeding its target airload. ECM will not allow more than 22.5 psi for more than three seconds or the throttle will slam shut and the BPV will open.
