Rear derailleur moves to much for each click - tried everything
So you originally had a have a SRAM 1x11 derailleur and matching shifter then swapped the rear derailleur for a Shimano 105. 

That is your problem right there. Shimano derailleurs are not compatible with SRAM shifters. The length of cable the shifter pulls for each gear change is different between SRAM and Shimano (and between Shimano road and mountain groupsets at 10 speed and above). That's why the derailleur is moving the incorrect distance for each gear shift.

You need a SRAM derailleur that is compatible with your SRAM shifter. You can replace the guide wheels in all but the cheapest derailleurs, so you could fix your original SRAM derailleur and re-install that.

Or you could of course replace the shifter with one compatible with whichever Shimano derailleur you choose to run.
