I would like to see the back to back results vs carbs. Also its important to note the type of build and budget. I am not anti efi but like anything to paint it with a broad brush and say its an upgrade period is incorrect. I recognize that there are allot of guys wanting to have the cake and eat it too but to say it is a better option depends on many things. For most like myself there is no benefit to the price/effort to convert to efi, it will not make more power and affect drivability enough for the conditions I drive it in to be worth while.
