Sounds like I'm going to use them! I was looking at MAP sensors and that part number is about 100 bucks and thereturn is another one thats like $50-$60 delco 2134658. I believe it is a 3.3 bar from a duramax. It fits directly in place of factory MAP.

The duramax sensor isn't a good option.

Take it from me and get the 2.5 bar from Gagetized on here. It's a direct factory replacement and good to 22 psi at sea level, which is way more than the part list in your post will support.

thanks for the input. it only took about 2-3 google searches to convince me not to use the 3.3 i just liked the factory replacement. ill get that one you mentioned then.

im ordering the MAP from gadgetized. and orderd an IAT from DIYautotune with a pigtail. from what i have found its the black and tan wires that i need to cut from factory MAF connector and extend to IAT a few inches from the throttle body? and polarity doesnt matter. once i have both of these installed i no longer need ANY of my factory O2 sensors, i will have my wideband in. Does my wideband need to connect to anything else? i feel like it does considering its got several connections/ harnesses on the back of it and the only thing i have is a VGA looking chord coming from the "in" connection out of my dash and the actual wideband sensor itself. after all of this i will be set up for a sped density tune which can be tuned to my stock PCM? i alos dont understand open loop/ closed loop but i feel like ive read tha has something to do with my wideband?

Open loop is no oxygen sensor feedback to PCM. Closed loop is factory calibration with oxygen sensor feedback for fuel trims.

There's another condition you can run called semi-open loop as well.

hmm ok. im guessing there are pros and cons to each? any particular one thats best for a daily driver?

closed loop

Silveraydo

ok done. thanks

in that case my wideband is just for me then correct?

FYI When u mount the Map sensor, mount it as close to the intake plenum as possible (on it is best).
