FP Black or GTX3076R
The GTX30 was fine when I ran it but you can only expect around 500 whp out of that turbo. For a turbo capable of 550 whp you will want a EF4, GTX3576r, EFR7670, or AMS 750R kit to get the job done. 20 psi spool in 4th gear will probably kick in around 3600 rpm at best but you will get the power that way.
3076 doesn't have enough turbine for the size of the compressor hence why the poor results on these cars. Either you want a 3071 and be in the low 400 whp range, or move up to the 3576 or 3582 and make 500+ and have slightly more lag.

I spoke to FP last week and production of the FP Black is temporarily on hold, it is not discontinued. They have a parts shortage.
This was directly from them, I think it was Robert. So until we hear otherwise, the FP Black is not discontinued and will be available again in the future when parts supply issues are resolved.

It's more the other way around. It doesn't have a big enough turbine wheel to match the already large compressor wheel. The 3576 and the 3076 share the same compressor wheel.
You're right. Was a rough night last night
