I do not know the price on it but you could get a performance chip that has modified timing and fuel curves that would be beneficial for your application, check with your local speed shop for the proper one.
The standard injectors are about 19lbs as I recall. These are usually increased to about 26 or 28lbs with cam change here. A bigger TB is also common.
