Greddy Profec B vs. Greddy Profec B Spec 2?
#2
New design
The Spec II is a digital version of the Spec I. Instead of ***** to control high and low boost there is a hi/lo selector and a more digital feel to it.
The spec II also has a much smaller boost control solenoid than the original Spec I big black box.
