Both the C/L and Pro-M 75's use a point measuring system . Thats why when you have a weird idle problem, people say turn the meter until it idles better. To get out of this, pro-m made the 77,80 and 83 and probably other meters that have a ring all the way around to measure air, regaurdless of the position its in. Thats why I prefere the Pro-M 77 or higher . Whatever you decide on, spend $100 and see where your air/fuel is at on a dyno. Then you will see how good or how bad it is.
