My low end still blows. Ideas to vastly improve it? My high end is amazing, but straight off the line needs work.

What mainly increases low end.

 

Sorry, I forget, what have you all done to the truck for upgrades? (Since you don't have it in your sig... )

 

hope i can remind.....go to search...

 

OK, after a short search, found a list...

 

low end help...... turn OD off (cheap). put on smaller tires (blows). replace 3.55 gears w/4.10 (expensive).

 

He already has 4.10 gears (off road edition).

That new Edelbrock/Hughes intake manifold might help.

 

Hmmmmm...trying to launch a 6000+ lb truck. Somewhere, I hear a conference room of pinhead engineers laughing.

What kind of low end are you wanting? Something that will obliterate you tires just by taping the go pedal? Or a little less?
Based on your current mods, all suggestions will be expensive, and may shorten your current engine life....
Here they are, in no particular order. Supercharger, Stroker motor, 4:56 gears, Nitrous, and sawzall.

 

A tune will help. Sct or B&G will get rid of the Torque management.

 

He's already got an SCT tuner.

 

e-fans or pullys??
