The digital pressurization system was also a VERY worthwhile mod. It completely relieves you of babying the system, and also got rid of the wheel on the console. It is set and forget, and will reset to departure elevation in case of a return.

By FAR the most important "mod", however are the sunscreens that tech ops designed. If I were a South guy on the -88/-90, I would be on the Bat phone up to North Tech Ops, ordering 200 ship sets !muy pronto!. They work VERY well.

With the overhead vents open, along with running the APU with 2 engines, it makes summertime almost tolerable.

I'm pretty sure with the MD-88s Delta ordered the larger APU. If it's on par with the MD-83, that APU will send plenty of air to both packs on the ground. The larger APU was an option back in the MD-83 days. Also, leaving the windshield heat at the gate helps tremendously too!
