40CU Unlock But No Governor Installed

Hey guys, I was able to successfully unlock all 40CU but I've been having a hard time getting a governor installed before and after the unlock. I tried the Cyan-Skillfish Governor SMU and the TT version without luck. It keep saying both cannot be found. I am in the correct directory and I also rebooted to make sure that the 40CU's stay active before that and they are.

That being said am I leaving a lot of performance on the table by not installing one?
