I had to try it. Seems to be a little quieter while idling, louder during the first 20% of pedal, and the turbo definitely spools up quicker. June 03 engine build. Also, my occasional "warm-start-rough-idle-poof-of-smoke" is gone. I just now filled her up to measure a full tank's performance. I am heading on a three hour trip to the beach Sunday, on Thursday I return home to get the boat and pull 3 more hours for a fishing tournament. I will post the results. I am very pleased with the results so far! Thanks.

Well, I disconnected mine right after my last post and it is definitely louder. (stock) It is also louder through the first 20% of pedal as Hot Shot mentioned. Doesn't bother me though, the louder the better. If I had wanted a quiet truck I would have bought a gasser. The turbo sounds terrific now, can really hear it.

This is to reduce engine noise at idle that has occured from removing the pilot injection. When diagnosing the EGR valve it is normal for the valve position value (EGRVP) to not change until the EGR duty cycle is greater than 30%. Broadcast Message 1067

Because if the default is OPEN, then unplugging the thing would have exactly the opposite effect as is desired, right?
