Whatever you need to tell yourself to feel better.
One truck engine make 500 Ft lbs tq at 3100 rpm’s. The mustang engine is good for a sports car at 400 ft lbs at 4250 rpm’s.

.
If we were driving around at 4200 rpm’s then there’s not as bad a deficit in power. Maybe some like to drive around like they’re driving a civic type R? But for 99% of truck owners torque is king and they generally don’t maintain 4250 rpm’s.
The 5.0 is a stout little v8 it just needs to rev (like you’d enjoy in a mustang) to get the power. If you like it - great. Enjoy!
Now for a tune, people should set reasonable expectations for the 5.0 bc you won’t change it’s higher revving power tilt much. The real power comes from a $10k +\- power adder that completely changes the truck and transform the little V8 to be a serious power plant.
