I'm trying to see if anyone has successfully removed the Oil pressure sending unit from the back of intake when doing an ls6 manifold swap. I really don't want to buy a new one. Is there a tool you can buy to help you remove it?
Also, is a tune needed to experience gain in hp/tq after the install?

A regular deep socket won't cut it, you will have to find an extra long deep socket to reach the bottom and yes it is 1 1/16. I found it a little difficult to use an open wrench cause of the clearance to the firewall. So I just went ahead and replaced it with a new one since I figured it's 11yrs. old it will probably break soon so I replaced it.
