Yes, the 48 Webers might be challenging to properly tune but the performance gain once dialed in is awesome!

Part of tunable means several sizes of factory and aftermarket "chokes" (slip in main venturi) can be swapped in and out. The flow "size" can be changed dramatically to suit driver tastes, altitudes, engine size, and degree of other modifications from inlet air temperature to size and lengths of exhaust components. Of course there is an near limitless set of combinations of fuel jets and air bleeds to go along with "tuning" for different engines and conditions.
