Sam, looks you "da-man". Rather than go through 40 pages of posts my question hopefully is quick. I by-passed the EGR and took care of the harsh 1-2 shift. Vac. at idle is 12"Hg. 0" Hg at full throttle. Some flaring at 2-3 with vacuum in the 4-5" Hg range. What is/are the target vacuum ranges for the intermediate shifts.
Heading down to the MB dealership for the orifices now.
Again, thanks for this great thread!
Welcome to the forum.

If it's flaring on 2-3 with 5" vacuum, you could try to reduce vacuum at idle to 8" and see how it goes. It might cure the flare if it's not too bad.
