The new Edelbrock 1912 800 AVS2

Bought one.
was looking for the 1812 - Thunder Series. My brother’s 800 thunder took .4 seconds off my et over the 750 AFB I had on it. But, Seems they are no longer making them.
The book that comes with it is in English and Spanish. I thought they sent me the wrong book, but I realized I had opened it from the wrong side!
BUT, the new book has nothing on tuning. No graph with jet sizes. Only the accel pump tuning notes if you have a bog, more the rod towards the carb body and refers to a page that has nothing on it about it. * and it’s in the top hole already! No exploded view w part numbers of the carb either.

Another thing I noted is the primary jetting is way different than the Thunder 800.
I attributed that to the new booster.
So, does that fatter booster cut down the actual CFM of the carb?
