Does having the vac line disconnected from the map sensor produces a more richer a/f ratio like Roger (furpo) said in other posts regarding this topic? Does anyone have theirs disconnected and noticed a difference in performance? If the ecu does use the sensor for other drivability issues other than for fuel cut/overboost, wont a fuel cut defender also play a roll by tricking the voltage? I had mine disconnected for a while and after reading what Roger said about the car running a little 'more' richer with the vac line disconnected, i hooked it back up. Yes, i know that a lot of you do this so that you can up the boost and avoid fuel cut. I would just like to know if the map sensor does more than just watch for overboost.
