What’s up guy! First time poster long time reader.

I have a 98 k1500 5.7 4x4 in amazing condition with 120k miles that my dad bought brand new in 98 and gave to me years ago. Now it has a 9.5 inch full throttle life on 35s. I’m looking to do mild performance upgrades on the engine to keep it daily driver worthy but have more torque to haul my small travel trailer and quads occasionally. Im not trying to spend a ton as my girlfriend says I spend too much on my toys (CTS-V, quads, jeep). The engine is mostly stock with a cold air intake, throttle body spacer, super chip, and true dual exhausts. What’s should be next on my list? Oh and I live in California so… yea lol

Thanks for the help!

Almost forgot I have to do a lower intake manifold gasket soon so anything I should do while in already down there?

Trucks with history are the best kind.

I have no idea what that means.

Good luck. California is insane when it comes to vehicle modification. EVERYTHING you do had better have CARB-approval documentation.

Step One: Replace the girlfriend. She'll only get worse/more controlling.

First Guess: The truck is already illegal and won't pass smog inspection.
