You'll get a TPMS light on the way to the track. I do. Once you get there, you just hit the 'relearn tires' button. It tries to learn for like 20 miles before it throws it again.
You can run the stock bolts. I think you'll figure it out when you go to throw the drag pack on. It's annoying af with the bolts. I change the rear wheels often, so it's nice to be able to do it quickly.
I got one from a scrap yard. If you hunt, you can find one. Visconti (I'm not sure if Jesse does) offers a discount if you bring your own ECU. You can save a couple bucks on an expensive process, so why not.
I've got those and a bunch more. They're all yours, sight unseen for $200 bucks.
I honestly have no idea what's in them, but a lot of the cards date back to the late 90s.
