Well... She runs!
I got all 8 injectors swapped out over the weekend. Went pretty smooth except for needing a couple crows foot wrenches, and a couple contortionist moves.
FSM claims to remove intake tube on passenger side (not necessary), and also to drain coolant and remove upper radiator hose for driver side (I was able to leave that in there and pull the wheel liner to access everything.
All seems smooth and quiet last night. I got it all warmed up and then gave a good 7 or 8 WOT runs onto the highway, got to 80mph no loss in pressure, no codes, just smooth power the whole way.
So... $7k later it runs again. Im gonna give it a few minor trips next week as I'll be gone the rest of this week for work. And if nothing comes up, then Im considering it all done.
Thank you for everyones advice, help, etc. I spoke with Harvey @ Exergy and he has heard about programming fuel injector flow rates in the ECM, but most likely for emissions related reasons. I also put a call into a local dealer to get their info. Still waiting for a call back. I'll update here with their response.
