Ok, one more question on the Holley jetting.

I swapped out my main jets (#72) for a pair of 68's
Then put the 72's in place of the 75 secondaries.
Everything looks, feels and runs great except for one thing.

The transition slots are a couple of numbers rich.
I say this because idle AFR is perfect, but as soon as I start into the throttle at normal driving around town speeds the AF ratio drops to 10 or so until I get up around 40-45mph.
Then when the main jets take over the AFR goes back into the 14-15 range where I want it.
I do a lot of driving between idle and 45 at light throttle, so it would be nice to lean those down a bit.

I know for sure I am still in the transition slots when the AFR is in the 10's
This where the transition air bleeds come into play, correct?

Thanks
