this will probs sound stupid but what is a boost return mod lol and do u need a boost return mod if u have an eaton charger is it just blocking of the breather hoses of the top cover? thanks :)
so i ant the only one that dosnt no then lol
im pretty sure no one has replied as a search will have given you your answer.
you do not require the boost return on the eaton, and all it consists of is removing the hose from throttle body to the rocker cover, and then running a hose from the oil breather to a catch tank.
oh ok thanks alot :)
