the exciting part of DI isnt what the car will make power wise while stock, but what it will make with tuning.
The problem with DI, at least the Ford DI is that it doesn’t take long to run out of fuel pump. And you can’t just call Aeromotive up and get a replacement/high volume DI fuel pump yet. They are mechanical pumps.
My F-150 EcoBoost is the most powerful non-nitrous one on the planet as far as I know. And the only reason it doesn’t make more power is we are out of fuel pump. And there is no ready solution.
You will be able to tune a NA DI 5.0 to your hearts content. But just poping on a “little” blower will probably have you running out of fuel. FRPP will probably have some sort of solution with whatever kit they offer, but it will take a while for the other companies to catch up.
DI could be a tuning "problem" for a while.
