Hey mustang

the foil delete is supposed to make the turbo whistle louder since it removes the insulation wrap around the hot side tube that goes to the Intercooler. I can't say that it made mine louder as when i did it i installed the WW and figured i would do it since i had it apart.
The EBPV (exhaust back pressure valve)delete is done to get more flow out of the turbo outlet by either replacing it with the larger bored out unit without the butterfly in it or by removing the butterfly from the old housing and plugging the holes where it was. It also is used to prevent the possibility of the oil operated rod that controls it from leaking and blowing oil all over the up pipes. I did this once again because i had the turbo out for a rebuild and put in the WW and also the larger oulet without the EBPV valve.
The AIH (air intake heater) is in located in the pipe that goes right into the Y to the intake manifolds you can locate it by finding the selenoid that sits with the one for the glow plugs and following the wire from it. It takes up a considerable amount of room in the pipe and i also did that when i had it apart and was ordering parts. you can get the plug it either has a hole tapped for a boost gauge or you can get it plain. I have read many posts that the heater is hardly used and then it is only used during long idle periods.

i forgot to add that if you do the EBPV delete there are 2 ways to take care of the acuating rod. I just removed cut the rod and plugged the hole with a pipe fitting plug. there is a write up about it somewhere on here on how to do it with pics. Or you buy the Non EBPV turbo pedistal. More expensive but less work.
