COPO, Drag-Pak, CJ II, (FX) Secrets

[GUMP]

It really doesn't make a lot of sense to take the throttle out. Modern ECU's have almost infinite control of timing. Shocks, tires, and gearing might want to be added into the equation when trying to figure out what makes the supercharged cars work so well?

I can tell you that every COPO that I have campaigned has run without limiting the throttle by anything other than the drivers foot.
