So I've got a 2005 2500HD with 6.0/4l80e as my daily (for now) and tow rig for the shitbox cherokee. I'd like to make a few upgrades to help out towing and whatnot. It really does great for what it is, and I don't have a desire to sell it for a diesel at the moment, but a few upgrades to help drag shit up the hills would be welcomed.
What have you guys done and what difference had it made?
Currently it has the cats deleted and 1-7/8" long tube headers along with a ported out stock intake box. All that together seemed to take my tow MPG from about 8 to almost 9.5 on the same route and same load.
I'm looking at possibly a torque cam, TBSS/NNBS intake, and a Blackbear(or other) tune
