Jim,

I didn't notice any loss in power after disconnecting the vacuum line to the EGR. Also didn't test 0-60 because I didn't want any loose chunks of crud to dislodge and enter the intake before they get a chance to get cooked and stuck to the side of the intake. 0-60 last week was roughly 13 sec.

I'll take a gps unit on the highway tomorrow morning and open her up and get back in a few days. In regards to a speed cutoff, I haven't noticed anything on my MB thats like my gas cars that start sputtering at 105, 110mph, etc. Are you coming up on a governor or is it electronic?

I'll likely remove the exhaust catalyst or oxidizer this weekend and weld a pipe in its place.

Hey...thanks again for the tips!
