Looks like I had another version of the mod that I didn't remove that wasn't completely fixed and the games was pointing to that one instead of the fixed one. So it looks like just deleting the demo- from the demo-sounds (in prototypes/entities and prototypes/turrets) is what allows the mod to be loaded into 1.1 .
Also finding the items with FNEI was pain as I couldn't use the in game name to find them. I found them their internal name worm-killer and worm-surfacer for the Seismic blast tower and Thumper respectfully.
