Road cranks, road BB shell, so it should work without any spacers... But it doesn't! My friend has exactly the same problem with his own cranks, also GXP, 68mm, road cranks...
They need a lot of force. Mine have play until they're about as tight as I can possibly get them with a hand held allen key. Still spin freely and smooth though
I've already broken a torque meter and nearly rounded the weak-ass aluminium self-extracting bolt off from torquing it up with my tough guy man muscles 💪
Think I'll remove the spacer, service BB and install the cranks with a big fat breaker bar

Maybe I'm not putting enough torque into it
