This is not quite right. The vac adv/mech adv dists only use the vac advance to 
give extra advance under light load at high speeds. The ONLY effect this has is 
to improve gas mileage. There's no noticable effect on torque or HP. Many 
people drive their FI cars for years with bad diaphrams and never notice the 
difference. This is one of the reasons that I keep a log of my gas mileage. 

On these cars, any advance due to the vac adv goes away as soon as you give the 
car significant throttle, so it's really inactive except when cruising.
