CLASS RACER FORUM - View Single Post - Question about fuel injection from a newbie

No reason at all you could not alter tuning by altering the fuel pressure with the factory LT1 injectors. I know NHRA Stock Eliminator racers that do it all the time. Turn the fuel pressure up on an LT1 injector, they have a finer mist as well. That is the point. Higher fuel pressure atomizes the fuel better. That is the reason for higher fuel pressures being used. Better emissions is the main reason. Very small power increase are simply a bonus.

I use injectors from FAST in mine.
