Procharge...
Worth it. Pro charger $5,1xx plus.. mandatory larger lbs injectors. Depending on HP.. mandatory PROM tuning "per" upgraded power- add- ons.
GM specifically tuned the 85- 91 TPI system incredible ratio to power. Taking on big block power. At specifically designed lower tuned Air flow.
end results. RPM.
Full benefit requires upgrading the intake/ heads/cam.
exhaust to handle the PC high volume forced air.
Price to performance wise. Calculations say no.
*** PC 5,1xx. More than. NA similar upgrades.
This does not factor- in.
Fuel pump upgrade.
700R4/ Dana 36 handling this HP/ TQ.
More upgrading/ modifying. price expences.
If you already owned let's say SSEi. porting, exhaust injectors. Tune.
Then again. NO need for a pro charger

Before the supercharger I had done:
-exhaust pipe system
-headers
-#113 Corvette aluminum heads
-Comcam mild cam
-1.6 rockers
-ported intake, plenum and Runners
-33 lbs EV14 Bosch injectors
-custom chip
-wideband gauge
-dyno 330hp
When installing the supercharger, I did
-Aquamist Meth / water injection
-TIAL dump with supercharger spring
-custom chip
-boost gauge
-FP gauge
-catch can that the crankcase is ventilated better, because the engine was not originally designed to work with boost
-dyno 403hp
Then a piece came off the 3rd cylinder piston....after which I installed the forged pistons
Now I'm installing a Meqasquirt engine controller that understands boost and it's from this century, after that a new dyno
Here is a short video about rebuilding
