(2)450 DP's vs (2)750 DP's

Ok it’s been a minute since last update. A bout of diverticulitis and the weather have kept me out of the garage. So I’ve plugged the middle emulsion holes and have the following tune

IFR .032 in the lower position.
IAB .070
Main Jets 55/62
MAB 35
PV 9.5
PVCR .082

Took wifey out for a little put around town so I don’t really have any numbers to share yet. I will note that it ran really well. A few things I want to address though.
Under light acceleration it gets a little lean. I can hear and feel it (just a little flat). It’s not super bad 15-15.5 AFR but would like to look into it. (IFR,TSR?)
Also at say 45mph+ cruise it trends upwards a little lean for my liking. Believe that’s about where the transition is tapering off before the mains come in. (IAB,MAB,IFR,TSR?)
And at a steady cruise anytime after 40mph I can hear an exhaust pop. I can’t feel it or see it in any of the gauges and I haven’t pinpointed any particular rpm, but it is kind of annoying to listen to. (Timing maybe?)

Seems it might be fat when the PV comes in. That will be determined after getting some #’s.

At any rate going to get it out soon, get some numbers and check the timing curve (when I can get a helper in the garage).

Feel free to post up some ideas for me to kick around.
