hi, i hav a 1983 FJ60 and i saw a desmogging thread that got my attention, is this desmogging really worth it?? do you just need to remove the smog related stuff?? do you need to adjust the carb??? how much HP will it increase? BTW this truck is a truck that i use in a lonely desert town so theres no cops around to check on the smog or loudness of the truck, so ill take any tune up. thanks 4 reading.
