I have an 8V92 DDEC 1 (198
I have an 8V92 DDEC 1 (1987) which has lost its top end turbo boost. It used to go to 20# and now tops out in the 13-15# range. Very few people know anything about this engine but it appears that the by-pass valve is not operating properly. I am looking for a parts source for the by-pass valve and any suggestions for other things to look at.
The exhaust manifolds have been checked and 1 replaced. New injectors and valve adjustments done. New fuel pump installed. Turbo boost sensor replaced and ECM checked. Excellent runner once up to speed but poor power under load.
Thanks to all who might point me toward the necessary part.
