I know for a fact that Pro Systems buys the same parts from Holley that I (and Shaker 455) buy so then it comes down to who knows more about how to tune a Holley carbed Pontiac Engine. Without a lot of research, the only two Pontiac names that come to mind were the carb Jim Hand bought from them and a carb used by a second guy.
Jim sent me the PS carb to evaluate and I found nothing in the carb that was anything special in the way of putting it together or the calibration.
The other gentleman actually tried several times to use the PS carb and actually had better luck with his well tuned BG carb.
I think his background with PONTIAC engines and carbs is limited.
