When a guy drives the truck every day and you start with a good demandate (might not be perfect) but I can tell you it is possible to tune them in so there is no vibration (talked bout cm2250 here based on Africa), Africa is a good ball park demandate, but I definitely custom tuned some parameters to get it just perfect for my trucks?, I consider it a decent starting point but I disagree with some pilot injection settings that make the engine smoke and run a little louder on cold start, easily fixed, just put those back to stock, also the c_cbr_alpha_chi_ Parameter is not included in the overlay meaning it is still set to 0, I prefer to set it to 4 as well, (no mode jumping), timing in it is set pretty close to run without egr and a slightly tweaked hpcr tables settings but I found it still slightly to much under 1/4 to 3/4 fueling when running the big cm2250 cpl, came up with my own timing tables, there is no vibration at 560 1850 torque, it is of my opinion that the isx is not really built strong enough to handle 2050 torque at low rpms for extended periods of time,
