i'm looking into stackin my current box(quad zxt) with TST. I think they should go pretty good together. however both boxes plug into the MAP sensor. how do u plug both boxes into 1 sensor? if u just piggy back them, which box should be first?
thanks for the help

 

Don't know much about the Quad but the TST should plug into the stock sensor, or go first as you said it.

 

I would put the TST first also.

 

I don't think the TST and Quads stack well. Both of them do timing, unless Quad has changed something lately. The original boxes that plug into the dataport will not work (at least on an '03).

If you do try the stack, make sure the TST is plugged into the MAP sensor first, then the Quad.
