Default Removing Hypertech Module (and 02 Sensor Help)

Hi, everyone. I wanted to ask about removing a stand-alone Hypertech module that may be affecting my 94 LT1's performance. I do not have a programmer and was wondering how dangerous or hard it would be to remove it without one. I'm assuming it isn't as simple as simply unplugging everything from the ECM (though that would be wonderfully easy), as I've seen through my research it requires a programmer. (Pictures below.)





I also was wondering if anyone had any tips about getting to the 02 sensors on this type of Vette, as I've had a... not so pleasant time reaching them and have not had luck removing them.

Thanks!
