"So how much should I lower the Small and Large Range?"
Errr.......a lot
Use this tune as an example.. 6.4 with whipple and hellcat 92mm tb.

Look at the changes in their entirety.
Airflow tables, driver demand, driver demand flywheel, TB prop gain, cam timing, etc etc
These all work together and affect each other so you can't just change one table and expect it to be all good.
I've helped a lot of guys on here with the same problem....the answers needed are all in the tune above.
(You will need latest beta to open it)
Oh..and do yourself a favour, upgrade to a hellcat TB or a whipple 102mm TB...the whipples need a lot of air.
You will get an increase of 1 - 1.5lb of boost with a bigger TB.
