My new stage 1. 278 frames faster due to better lag reduction, and a new discovery at the boss that made him way faster. Ignore the comment in the link. I accidentally typed improved stage
2 instead of 1.

Some parts actually look a little less impressive, but it saved time. I don't know if I should try the boss a few more times, but I'm very pleased with my time at this point. I think I'll take a few days off from this now.
Edit: Trax TAS Production update!
I had stalled on starting up again, but I've finally started level 2. There are only 4 levels and an end boss in this game, but it's still been pretty hard due to lag reduction. If you don't get rid of moving objects quickly, it could cost you up to 10 frames. Though the trucks that contain power ups don't effect it too much, and sometimes it causes extra lag if you shoot a bullet to kill it. If you just leave it alone, sometimes it'll save time.
