Not sure if anyone said it but lagging your engine is terrible!!! You are making spark knock and creating a nasty stress on internals and bearings doing this. Know what else? Your tranny, clutch and rear end hate it too!
Now I have seen this asked....why do this to your engine???
A comparison that anyone can relate to is your lawn mower. Normal grass cutting, its factory settings allow years of trouble free happiness. Take the same mower and try cutting a pasture or tall grass where you're bogging the engine continuously and that engine won't last a month! You feel the mower shake violently, just like lagging your truck in too high a gear.

I agree 100%
The drivetrain just doesn't "feel" right, if its not revving above 1100rpm while moving in gear.
