What would you do? I bought an '07 Tahoe with a 5.3. Before everyone dogs me for how bad they get gas mileage, what would you do to improve it.

Here's the list I've comprised.
Pacesetter headers, Full Exhaust (with a highflow cat).
102/102 Fast Truck Intake
5.3 PRC Stage 2.5 Heads
CAI
3.23 Gears
Tune
I've taken the back seats out as a "weight reduction" but that's about all I'm going to do.
Will any of these mods have any effect on it being an LS4 motor, and having the Variable Valve Timing (skips a cylinder ever other cycle for gas mileage)?

intake, exhaust and tune. does it have a manual fan or electric? if manual, swapping to an electric will help.
just don't forget, your ACTUAL savings from these mods will take a very long time to make up for how much your going to spend on them. so personally i'd leave it stock unless you want exhaust for sound purposes. and taking your seats out really aren't helping much. i think people expect to much out of "weight reduction" unless your really going for every last tiny bit. or unless your really stripping a car for strictly racing purposes.

It's rated at 14 City 22 Highway with the VVT 5.3. If I got 22-24MPG Highway, I'd be ecstatic.

So you want to spend $1,000 + on heads and almost as much on a fast intake just for better fuel economy?
Sell the truck or drive it as is. Even if you got the milage your looking for, it would take a very long time to pay for the modifications you want.

I get 19mpg from my 1999 5.3 Silverado 2wd (mostly highway with some towns mixed in, hilly terrain the whole trip)
Underpowered turds do not help fuel economy since they just lug around too much. My old 93 Chevy short wide with a v6 got 14-16mpg highway and you had to turn the a/c off just to maintain 70mph up hill.
OP:
port the tb, cheap headers/exhaust, replace the stock intake tube with a smoother CAI type with no silencers but use the stock airbox, 87 octane tune, and you should pick up a little
might not be enough to offset costs for a very long time though
