no. this is what i mean. if you swap on a tb that has a location for a map sensor, but your engine already has an IM or firewall mounted map sensor, you will have to plug the TB hole that is expecting the map sensor. otherwise you'll end up with vacuum leaks.
which brings me back, the only problems you'll run into are vacuum leaks from components such as tps, iacv, map, fitv etc.
you can probably seal it up with silicon and use your existing map sensor. that will be your quick fix around an extra sensor location
