I am going FI and was told I need the GM 3 Bar map! I looked up the part number on LS1tech but when I got the part it looks diff then the one I have now.

I want to mount it in the same location as my other one but can not figure out how to do it!

Any photos or directions?

THANKS

The three bar isn't a direct replacement and will need to be relocated. I have a vacuum manifold and that's where mine will be going when I switch to it over the 2 bar.

^this. No one makes a direct replacement. Just run a vac line to it and mount it somewhere safe.

actually the duramax 3.3 bar map is a direct replacement

3.3 bar? Does that work with HPT's 3bar OS? I know you can't run 2.5bar maps on fbody OS's for example...

I dunno.

I went for this one because it fits directly into a LS3 manifold.

I don't think the connector will fit a LS1/LS2 harness. You might need a pigtail.
