I dropped to a 3.2 pulley. Tuned it.
From 259HP & 254TQ
It got 266HP & 267TQ
from 5 PSI went up to 7 PSI
No Knock, just .01 to .04
It produced 12 to 16 Horsepower till 5000rpms
From 5000rpms to the redline, it only gained 5 to 6 HP
I believe its time for springs and retainers.
I will upload some pics of springs I have with retainers for help.
The guy who tuned it told me it was not producing more horsepower up top
Because of the supercharger getting too hot.
It may be true. But i dont know
