Got a vac can that worked and Re did the timing curve. 16 initial. Running a lot better, still bogs(rpms drop) when the secondaries open. Does not do it in park anymore.

Easing into it like you said helps a lot but there is still an rpm drop

Takes off better now when it catches up tho. I get that it might not be the best performer off the line but the rpm drop when the secondaries open is a carb/tuning issue right?
Im just trying to get the best out of what i have at the moment until i can add the things it needs, i feel like i should be able to remove this rpm drop with tuning. Am i just dead wrong?
