Supercharger and What else do I need? 1990 Saleen Vert 5spd

For starters, we need to see pics of the car

Now that’s what I’m talkin about! NICE!!!

Just out of curiosity, why do you cover your license plate? Lots of people see it every day. Not trying to be a Richard. It's a legit question.
Badass fox, by the way.

I have a Paxton Novi 1220SL on a completely stock engine down to the MAF. All I’ve done is replace the stock fuel pump with a 255lph walboro unit.

I do have full exhaust though.

How does your car run? Surging idle or no issues?

I’m hearing that it all depends on the boost and output expectations. But the stock system doesn’t handle the additional forced air well without a bunch of upgrades

If this was directed at me, car runs perfect, just like stock up until like 3,500rpms when the supercharger kicks in. The 1220SL is a 'low boost' kit (5-6psi) so its all good with everything stock (except the fuel pump). It has an FMU as part of the kit.

I have other issues going on with my car unrelated to the supercharger where i get complete power cutout at like 5k rpms and something is wrong with my cylinder #7 (maybe leaking valve stem seals or bad piston rings, or something else) where i keep fouling that plug but i know its unrelated to the supercharger because the issue was there when i bought the car prior to putting on the Paxton.

I have plans to add 24lb injectors and a calibrated PMAS MAF, different FMU disks to make that work, as well as a pair of TFS heads i plan on installing all at the same time. I also have a bypass valve kit that i will put on as well. Once i figure out the tuning side of things i'll go bigger TB/EGR and probably go back to a stock 70MM SN95 MAF (which i have, to keep it 'stock' looking), as well as much bigger injectors (like 42lb +). But i'm not at that point yet.

Everything i do to this car is/will be SMOG legal in the end. The 24lb injectors and calibrated MAF (and bypass valve) are the only things i need to figure out since those are not SMOG legal, but they aren't on the car right now. I'm worried even with the FMU i'm maxing out the 19lb injectors. It passed SMOG earlier this year no problems though.
