i have fuel distribution problems with the siamesed port.it has the biggest effect at idle. i am running multiport fuel injection, with 2 injectors per port @ a 45degree angle. at idle #1 cyl liked to grab all the fuel charge for both cyl 1 and 2. to correct it i now fire the injectors once per revolution and have split the harness so injector #1 fires 180 crank degrees off from #2 injector. that helped the idle. @ higher rpms, like 1500 and up it is not noticed.
turbo 6 do you run the divided ports with your setup? tom
