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.

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?
