Thanks man! I went back to post #2 and made it more of a build thread than it was before:
2007 LX470 Super Cruiser build with Elate Mfg Supercharger - https://forum.ih8mud.com/threads/2007-lx470-super-cruiser-build-with-elate-mfg-supercharger.1288831/post-14520922
So far mileage around town has been about the same 10-12 MPG depending. I'm using a lot of throttle too

I want to get it out on a longer road trip to see how it is on the highway.
So far I've only seen a max of 5.4 PSI on my gauge and Travis says I should get a full 6 PSI based on the calculator. It's probably a restriction with my intake tube. I did what
@Wadepat2 suggested and removed the lower section of the airbox. I used some big zip-ties to keep the air filter in place and did some pulls. It didn't increase the boost PSI at all, however, so if there is a restriction it's in the crossover tube itself. That was also with the bigger pulley I haven't tried it with the new one yet.
