Still no love. I'm out of time for this weekend.
So, what I've done this weekend is:
1. removed ALDA
2. disconnected EGR and blocked hose
3. disconnected Air Recirculating Valve and blocked hose
4. disconnected wastegate line and blocked hose.
5. connected gauge to manifold port. Got -.25psi at idle, +.45psi max on the road.
Road test after each item.
Same good pull off-the-line. Same bogging and smoke on hills and moderate to heavy acceleration.
Guess I'll plan on pulling more stuff apart.
