As a tip on the issue with the wrong cruise values, always make sure to start the PDCS, enter your weights and things and allow the automatic updates on the 'WIND' page (submode), which is the 0 (zero) key on the numpad.
This will give you much better predictions and seems to cure the problem with the way too low cruise EPR values. Still, it plans for some 0.708 cruise which looks too low for the 737 in my eyes. So it's no 100% cure. :-/ Also, any mod on the FDE isn't calculated, so that PDCS value only reflects the default CS737, not the ones running the (in my eyes) recommended FDE mod.
For proper calcs on the FDE modded planes, stick to the great work of Bud and Paul.Here's how the pages of that 'WIND' submode should look like. Note the 'YES' on every page, which has to be confirmed by pressing
ENT. The unit starts up with NO, so that's why you should check it.
