A small bug-fix for conventional subs PSL values in LWAMI 3.11 will be needed. I checked all PSL data for this type of subs in DWEdit and I must tell you that they are quire correct. Molo & Co. did good homework here as opposed to SSNs!
However Improved Kilo is slightly overrated having PSL=55 which is not a case against other contemporary submarines. So I changed this value to 56 which seems correct. Besides Chinese Yuan-class sub is also slightly downgraded here - I think as for now her PSL should equal 57 not 58 because this is quite advanced design still under development with Chinese AIP based on Stirling engine probably installed.
All in all Russkie Kilo-class subs never were top-notch as Russian propaganda twaddled long time. First 877 Kilo-class project was noisier than Western diesel subs of 1980s era (Type-209 Mods, Vastergotland, Yushio) and widely marketed 636 Improved Kilo from 1990s is also noisier than Ula and Walrus subs for example. Besides without towed arrays Kilos are now crappy freaks.
Chinese conventional sub's technology is now on par with Russkie Improved Kilo and is still progressing forward! If Russkie Lada-class is really a disaster and Chinese mature much more prospective version of AIP technology they will outrun Russkies also in this area. Well, everything looks like that...
Unfortunately LWAMI's PSL tables (PSL vs speed for playable subs) are completely flawed, I am afraid. Research this area once again LWAMI (now maybe MLTLAMOS) Team.
PS. I couldn't find the following conventional sub classes: Upholder, Zwaardvis, Sjoormen, Soryu, Sondermanland. So Molo & Co. should add them to the game at price of removing some silly outdated and mainly scraped stuff like Romeo, Foxtrot, Oberon etc.
