I've found them for $80 a piece new shipped and was wondering how well they work

pass and get the jhm one man its the same price and its garruanteed it works .. plus all that piping could be hard to mess with and i think it makes lag with the extra piping since it has to send the boost or vacume signal and would take longer... correct me if im wrong but anyways the jhm one is awsome and in car adjustable

At $80 shipped i'm getting it over half the cost of the JHM.i know the JHM is good but i was wondering if anyone had exp. with this one. the main reason for asking is like you said it has a long vac line.I don't think this will hinder much more than a .1 sec of a delay.Maybe i'm way off though.Just wondering.
