that would be too much timing. yes they are the same connectors. to stack a fueling box, you put the male (fueling box) connector into the factory female map sensor, then the male (timing box) into the female (fueling box), then the male factory map sensor into the female (timing box). i makes one big loop. just remember fuel first. i am running the edge ez/quad xzillaraider stack now. but only one timing box at a time. the comp is basically all you can run unless you stack it with a smarty and do not run the timing settings, run fuel only. if you buy a tst/quad/blue chip on the other hand, than yeas you can run a timing box or smarty timing setting with them.
