Hopefully nobody. Not sure why anyone would want such a thing.
Several companies, us included make one with a plate under the TB with regular injectors, but can't see the need for true TBI with 4500 size air flow
So a 4150 rated for 1200hp is ok, but us guys that want the same thing without an adapter in a 4500 is not...Logically, your argument makes no sense...I can't understand why you wouldn't.
