Standard sc pulley+ 178mm crank pulley

Yes it is the same as the 178mm cp in your link

I do have a spare stock sc pulley that i may get shaved a couple of mil. :-)

re my 20psi reading ,it was via the obd on dashcommand so may not be exact.
I know Les says he has seen 19psi at sea level with just the 178 crank, so its close.
