If you are FBO you should not be in STX. You also cant run more than 15% ethanol in any street or street touring class. E30 puts you in ASP, also Meth injection is banned from all classes. If you are catless and have an upgraded intercooler then you should be in ASP. In STX you must have a >100 cell cat and you can't modify anything from the turbo inlet on. Also anything other than the stock turbo would disqualify you from any street or street touring class.
Hopefully you're still on the stock turbo or else you will be in XP. Is it the end of the world? No, but you'll never be competitive in the PAX.
So to summarize you should be in ASP. All of your engine mods, except a turbo upgrade, are legal as well as your fuel and tires. For reference, all of this info came straight from the SCCA rulebook 2020 edition.
