i have one in my N/A car with 4.08 gears/
it shifts really hard and fast .
it was really quick at the drag strip ( bone crunching shifts at 7800 to 8000 rpm).
car ran slower but the 1/8 and trap speed where very high.
problem is that the uprev *car not tuned * closed the throttle body's on me when it shifted. and it stalled coming of the line. car ran way to rich.
the 4 to 5 shift is night and day different.
my stage 2 Sc will be going on soon.
