I've noticed more sound (and action) from the turbo at that speed. Prior to TO replacement the turbo boost was nearly non-existant.

This weekend I hope to tune/check the boost preasure, ERG, and anaroid compensator base adjustment with the help of my uncle Robby.

I'll also be doing a 1000mi of driving so I will soon know what my post TO fuel economy is.

mysoder,
I bought mine after its TO removal,but it is
quick for diesel and fairly revvy upto 4500rpm (when not comparing to 9000rpm S2000). I was averaging 30mpg in cruising speed of 80 mph with full A/C operation in 100+ ambient temp.
Post your mileage and performance after your trip.

We'll now i know what everyone with a properly running 6cyl diesel is so happy about.

I just spent the labor day weekend with my uncle Robby and we got to the bottom of my 300TD performance issues.

After checking the boost (.8+ bar) and finding no fault there, we proceeded to bypass the overboost protection switch. That was the problem! It was protecting me from fuel wasting acceleration.

I went from 20sec 0-50 times to 10-11sec. My fuel economy went down from 30mpg to 25mpg, but I've been gunning it at every intersection to make sure it's still working. :)

This weekend I cleaned the banjo bolt and the vacuum line from the intake manifold to the crossover switch as per the instructions in Easley's very complete FAQ (and it works for the 603 engine) found at:
http://hsb.baylor.edu/html/easley/autofaqs/boostchk.htm

I'd measured the boost pressure on that line originally and assumed since I saw spec pressure that the line was clean enough. I was WRONG. The banjo bolt was nearly completely clogged and cleaning it made a noticable difference in power. The trans shifts at a higher RPM at full throttle and I can accelerate up interstate hills in high gear with a full load. (And by full load I mean six passangers (two are children) and the luggage including pumpkins on the roof!)

I haven't had the chance to try a 0-50 to compare with the numbers I had measured over labor day, but I'm sure that I should be in the 9sec area. Not shabby at all for a diesel wagon.

And Ken, I have a very satisfying growl from my engine. Is it possible that this can get any better?

Good evening, Mike --

Please make sure that you take care of the problem related to the overboost protection switch ASAP. You do not want to drive your car with it inoperative . . .

One thing that is not mentioned in this thread on trap oxidizers is the very real potential of cylinder damage with vehicles that have a history of failed trap oxidizers. The material inside the trap can make its way into the cylinders of the engine via the EGR (really; trace the path) and a new turbocharger (discussed extensively in this thread), if needed, is obviously not gonna take care of that problem.

Still -- it's a nice touch for MBNA to pay for a recall on a car that is now 13 years old . . .
