Dang, how does that 05 motor run? How hard was it to stick in the 03 Ex.?

throttle plate removal effect engine braking in tow/haul?
Does the removal of the throttle plate effect the engine braking effect in tow/haul mode with the auto transmission? I tow, and would hate to see any decrease in engine brake efficiency as a result of the throttle plate not being able to be closed.
I am guessing that not only do the turbo vanes close down, but probably the throttle plate is also closed during tow/haul braking. Anyone confirm?

I suppose the reason I am an advocate of disconnecting it is all the good it did for mine, both in terms of performance and economy. Nothing drastic, but nonetheless noticeable. The only thing that is "abnormal" is 2 measly trouble codes. Some havent had quite as much luck as I have with it.

I am going to unplug EGR as well but am a little confused regarding noise level. In many previous threads I have read that people feel that there truck may be a little louder after unplugging EGR, now in a couple of responses here, guys feel it may be a touch quiter. Is there any mechanical reason why it may be quiter/noisier ? Can anyone confirm their noise level ?
Also, by having the EGR unplugged, will the truck take longer to warm up? (important here in our cold winters) Thanks for any responses.

Truck is two weeks old. Build date is May/04. It also has a different 04 1/2 model year flash as well because at a local diesel performance shop here, they tried to load a Superchip Tuner program and it wouldn't load no matter what. Afterwards they said Ford had a different flash or system out for the 04 1/2's . That is the first I've heard of that.

I have heard that Ford is about to release a new flash. But I have been hearing that since January. It is possible there is a flash that is going in new trucks but not released in the wild yet.

Maybe I'm WAY off base here... but I'll post it anyway :-)
Seems to me that stopping the exhaust from going back into the intake stream would make the truck more effecient in that the exhaust gases CAN'T burn as well as a pure charge of diesel...
MY take on it is that it should burn a little better....
so maybe that DOES make the explosion more violent, but more effecient, and therefore needs LESS to do more :-)
