This is now a more extensive update. This started as just replacing the egregiously bad stock tower and then adding apron lights so the airport wasn't pitch black at night. Well, it's gotten a little more out-of-hand. See update below:

**IMPORTANT: A couple of users identified an issue with ground services including jetways and pushback tugs at some of the gates. After doing some testing with a few people we found that the issue also exists in the base KBOS from Asobo (ie., it happens without this mod as well). Specifically, you cannot use any simconnect systems (toolbar pushback, the FBW EFB, the CRJ EFB, etc.) to call for ground services at the following gates: A13-A22, B7-B12, B15-16,  and the West Cargo Ramp.

Workaround: You can use the in-game ATC, tune to Boston Ground on 121.9 and request the services. If you request the Tug through the in-game ATC, once it is connected, you can use the Toolbar Pushback mod to do the actual pushback including a pre-planned pushback.

This is an odd bug in that it affects the Asobo KBOS as well, but replacing all of the gates  in this mod didn't change the behavior. All of the problem gates are west of a very well defined line - nothing east of that line is showing the same issues. I will be filing a ticket with Asobo, but if anyone has further details or insights, please send me a private message. Thank you!

v1.3 UPDATE:

Small-ish update this time. A few new buildings and some surface markings. Planning on adding the UPS buildings as soon as I can get some good air-side reference photos. Then I will probably move to the South Cargo Ramp.

• Added custom-modelled maintenance hangars for American, JetBlue, and Delta at the North Ramp
• Added Taxiway "Spot Markings" around the terminal. These are mostly useful when talking with ATC (i.e., on VATSIM) - Includes the (in)famous Spot 7: "Push into the ramp your discretion, advise at Spot 7 ready to taxi"
   

v1.2 UPDATE:

• Added a custom-built and textured Signature Flight Support over by the GA Ramp
• CAPE AIR GATES now avaiable - Cape Air flies Cessna 402's out of C27, so 10 small space are there now
• Adding the Cape Air gates meant re-doing all of the gates for the airport as well as taxiways.
• Re-did all ramp, gate, etc. markings to reflect reality as best as possible
• Added custom taxiway surface markings where appropriate (Instersection markings, ILS and APCH hold short markings, anti-certain-famous-celebrity "TAXI" marking on Taxiway Mike, etc.)

Please let me know if anything is amiss - this is a TON of work to revise all of this, and it's likely I missed something. If you find it all valuable, please consider tossing a dollar two my way via the Donate button. Thank you and Enjoy!!

v1.1 UPDATE - Due to popular demand, I have added arpon floodlights by the gates, etc. I tried to place them as accurately as possible based on satellite images, but if anything is incorrect, let me know!

To re-iterate, this does not fix any weird taxi issues, unrealistic terminal, garage, etc. Just the tower. (and as of v1.1 - Floodlights) :-)

There may be downstream issues - if anyone notices problems, please let me know and I will try to address quickly. Enjoy!
