I used to have an 03 HD 6.0 l Silverado, I recently replaced it with an 07 HD 6.0 l. I've noticed that this one has tons of torque management compared to the older model. Especially from dead stop until about 65 mph it's super sluggish and with a big service bed on the back full of tools it makes it terrible trying to gain speed entering the interstate. Does anyone know of an easy fix or tune for the 0 to 65 issue? I'm not interested in tuning the entire thing for high performance, just want to be able to give it full throttle when I need it like my old one was.
