Appreciate it! The reason we changed all our trucks to 4:10-4:30 gears from 3:54 was for hauling purposes. The 3:54 actually was really laggy at a take off.

Then if the 3.54s where laggy that leaves you with fuel and tuning. Load drives the charger.

Since you aren't towing 30k a different set of gears will load the engine more, boost would come on stronger , even a stock turbo with 3.54 gears spools much quicker than our same truck/setup with 4.10s.

Increasing mechanical leverage over the engine increases heat rejection in the cylinder, that drives the turbine.
That was under my blanket statement of "iron changes". ?
