Sps upgrade is a special coating on the rotors. It should make the unit roughly 8% more efficient/ more boost.
If you plan on going 69mm pulley and still wanted to squeeze just a little more the sps might be the way to go, however at that point a 335 unit with the largest pulley IIRC 85mm pulley makes about 14psi would probably be a better option. If you had plans to build the block and wanted to push a 335 unit as much as possible the sps upgrade would be worth it at that point IMO.
