I’m not sure who’s setting them up for you but I’d say it’s very doubtful that 48 IDAs will be bolt on and go. The good and bad news with IDAs is they are very tunable, but do need to be tuned/jetted properly. You should search the subject and buy a mag/tutorial if you have never owned and run them. Have you selected a cam specifically for IR IDAs? If not you should do so and this is true for IR in general for either IDAs or EFI. Without proper cam fuel reversion can be extreme and potential fire hazard. When properly done, IR EFI will afford better street manners. Most ECUs should allow cold start routines, better timing of when to introduce fuel pulse, ability to make altitude/barometric pressure adjustments (do you routinely experience significant changes in altitude in your driving?) and in general, easier tuning if you’re modestly computer savvy, as all can be accomplished by lap top computer as opposed to physically changing jets, and IDAs have a lot of them. IDAs also do not have choke and are really race carbs. IDFs have chokes. Most ECUs will enable significant advantages in ignition tuning as well.

IMO, IR induction is not for people that are not tuners. I dont want to discourage you but like any custom engine build, parts must be properly selected in combinations that compliment each other. If the attraction to IR is primarily looks and the expectation is bolt on and go, I think you will likely find it unrewarding. If you are reasonably knowledgeable in engines and tuning, and like to do so, you can achieve nice results.
Best,
