My $.02? Take out the LLoydz controller entirely so there are no variables in the equation. If something goes wrong, and the LLoydz controller is not "in the mix" because it isn't on the bike at all in any way, then it will make any potential troubleshooting a lot easier.
Besides, wouldn't disconnecting the ground wire disable not only the LLoydz module but also the fuel injectors into which the LLoydz is connected since there'd be no power getting to them through the LLoydz controller anymore? If that's the case then you're going to have to remove the LLoydz module no matter what.
My gut tells me to just take the LLoydz controller completely off your bike first and then install the Power Commander. It's a pain, but it will no doubt be worth the effort in the long run.
