I ran the car on the dyno last night to get the A/F ratio set better, the car made 340 rwhp and 391 rwtq on a mustang dyno, but it was on a A/F ration of a 11.6-8:1 all the way through the rpm range. What should be a safe A/F ratio till i can get it chipped? i have a wide band so i can monitor it. any help will be greatly appreciated.
