Vortech V-2 S-Trim FMU
Does anyone know the ratio (4:1,8:1) on the FMU that comes with the 6-8 psi Vortech V-2 kit for the 1988-1922 TPI F-bodies?

I think it is a 8:1. Mine was, but I bought my kit (A-Trim) 8 years ago
Right now I have a 6:1 with a bleed valve which can go down to 4:1.

Here is the response I got from Superchargersonline.com

Vortech uses an 8:1 FMU in their 1988-1992 5.0/5.7 supercharger kit.
Here is the injector/recalibration layout:
12:1 = 19lbs Injectors
8:1 = 24lbs Injectors
6:1 = 30lbs Injectors
