Who here is using this? I have a delteq and I am trying to get my car back on the juice. The delteq website said that the trc-1 is the best choice to retard the timing. Can anyone give me some info on it? Can it be used with a window switch, so my timing is only retarded during my window that I am spraying? or does it retard the timing all the time? in which i would try something else...
