got a question on those two tables. in the process of building a motor in a customers 5.9 and going to see how much power can be squeezed out of it with cam, 6.7 head and single s467 on it with 100hp injectors and a stroker cp3. looking for some advice

Yes, with a single S467 and the other mods you mentioned in your first post you are definitely going to need to adjust them. My assumption is that this is going to be a street driven truck.

Yea definitely adjust. Both timing and duration. I like to start with a bit more pilot timing and taper it down as load and main timing go up. Keeping pilot timing higher while main is low, and vise versa. For duration it's a bit more trial and error. With big injectors you can sometimes end up with a bit of a lope when coming down to idle if you don't drop duration down, or if you drop out too much pilot duration it can get a bit noisy. A bit of trial and error.
