Ok I need help on tuning my car. I have the Ford falcon wagon with the Paxton supercharger. Well I have a 650 blow thru carb. The jets on the primary are 74 and the rear is 78. When I am at idle it is 14.7 to 15.1. when I Cruse the car at 55 the a/f is 10.8 to 11.3. so if I go down two jets sizes, will my a/f go up to 11.5 to 12 .5. thanks for your help.
