BB30 crankset installation issue

I'm trying to replace the stock FSA Gossamer BB30 crankset on my Cannondale CAAD10 with a FSA Hollow Carbon Crank BB30 (It's essentially an SL-K). The torque spec is 36 NM for the new crank and I'm using a calibrated torque wrench to install the new crank.

As soon as I reach roughly 28 NM of torque on the new crank it stops spinning freely. It still turns smoothly, but there is a significantly more resistance than would be expected. The resistance gets worse the more torque I apply.

Any idea what could be wrong? I have installed bearing covers on both sides. I tried a space and the wave spring washer on the non drive side. I've also tried no spacer but the spring washer on the non drive side. Both yield the same result...Crank is clean and lightly greased on the machined portion of the spindle.

Please help! It's a nice day and I want to get out!
