I’ll acknowledge right now this post will be of no help whatsoever......
The fact that you have to make so many changes to get the carbs to work well on that combo is likely the first clue that they aren’t the best choice for that application.
From a strictly pragmatic standpoint, I wouldn’t have bought carbs that I didn’t already have tuning parts for, and were always a couple of days away.
There are other issues in the combo not related to the carbs themselves that IMO are exacerbating the tuning woes.
You have the Weiand TR, right?
The one with the giant plenum area under the carbs........ that you figured weren’t big enough, so there’s like a 2” spacer under each carb?
Besides you thinking they look cool...... what they also do pretty effectively is kill off/dampen/delay the signal to the carb.
I’ll follow along to see how it all works out....... but I think you’re going to have your work cut out for you.
