Outer Limits 4x4 Board

goanna where in 4wd monthly has after market injectors for sale at $59 each. would you think you could only use them once turboe'd or use them standard, also does anyone know wether they are bigger, like i mean you dont want to be driving down the road with a hell of a lot of black smoke coming out from over fueling. if anyone has any info on them would be great thanks.
