Thats what it sounds like...
If you are using SVT LIM and 3L heads...then you must have port matched the heads to the intake. Since both parts are now conforming to 2.5L standards, you would be using the 2.5L Fuel rail, not the 3L one. As far as its limits...i dont quite know what you mean, but someone else can take a stab at it. And thats a pretty mighty goal to be setting!!
