MD-81 and MD-82 range issues

MD-82 has shorter range than IRL ( 2102 ingame compared to ~2359 IRL). Sources: https://skybrary.aero/aircraft/md82 https://www.globalai...ons?specid=1011

MD-81 has significantly longer range than IRL (2244 ingame vs ~1800 mi IRL) Sources: https://skybrary.aero/aircraft/md81 https://www.airliner...md-81828388/109

These issues makes the MD-82 and MD-88 effectively useless. (Not that this would make the MD-88 worth it but I digress). 

Interestingly, the MD-88 which also flies 2050 nmi, has correct range ingame, and has no differences from the 82 apart from EFIS, so idk whats up there.
