Thanks again. The dyno sheet for my engine shows 16.5 psi boost @ 2100 rpm, down to 15 psi at 1500 rpm.

Thanks for the information. Different injectors and pump setting from the endt673- and a different turbo?

I am looking at a dynamotor sheet which lists the engine as engine model # ET673-260 with a serial # of 4B7058. What is this engine? The sheet says 260 hp @ 2100 rpm. The dyno sheet is showing 188 horsepower at the rear wheels with 15 pound boost and exhaust temperature at 850 f.

There are multiple wiring diagrams in the Wiki section of this website.
