You won't really know until you have it under load. My impression is you can do much better than a locked out curve, and it will ping if you'r not spot on with the timing setup and carb tuning.
I had it locked out for the start up only.....started at 22* and once broke-in moved it up to 30* and programmed in a 10* start retard in the MSD ECurve Dizzy.......Once in the car I will start to play with either a mech or vac curve or possibly a combination of both.....these ECurve Dizzzy's are awesome :love4:
