Have a great day,
Camshaft timing will always have an effect on engine performance, it just isn't as drastic on a Diesel engine. I have watched the changes on a chassis Dynometer with the delivery set at 24° BTDC. A mere 4° of advance is worth around 4-6 lbs/ft of Torque on a good running engine.

Setting the '05' cam at 'zero index,' advancing the pump timing to about 28° BTDC and increasing boost pressure to 1.0 BAR makes for a very nice running engine...Bert
