What should I do?

[dylanZ71 AZ]

About to get 500 to spend on my 04 tahoe, I need some ideas for what to spend it on. A few things I've thought of so far are headers, leveling kit, tail lights, brush guard... trying to get the most out of this 500!! Thanks guys.

Would be helpful to know what you've already done to your Tahoe. But if I were you, and all maintenance was up to date, I'd contact Black Bear for a tune. I don't have one yet as I'm wanting to do a couple other things first, but bang for the buck and customer testimonials say it's like driving a new truck. If you could swing it, Long tubes and a tune would net you 30-40 horsepower.

Yeah, I'd agree with being sure all your fluids and maintenance is up to date. Otherwise those mods will be sitting in your driveway waiting for repairs.
Maybe a brush guard with a light bar?
