Re: My tuning skills have hit a wall.

Terry, I agree with you but technically FI goes lean and rich constantly so it never is actually perfect. If your AFRs are moving around then your air bleeds are not correct or mis sized. Sometimes they MAB and metering block package need increased as a pair. Same curve but less responsive. There are guys out there that can get a holley about as good as FI.
