    A gear swap to like a 373 and a good custom tune and you will be well on your way. That is after you install a CAI and exhaust. Good luck man

    other less expensive upgrades are throttle body spacer, lightened pulleys, low temp thermostat, MAF sensor. most of which are not too bad hard to install, after that your gonna have to spend some money if want noticable results. 5.3's are a really good powerplant but the only thing they got going for them from the factory are vortec heads! if u wanna make some true power u'll need an engine rebuild and upgrade all the internals, AND THATS VERY EXPENSIVE!! but if u look in the right places you can probably make around 500hp for about 2-3 grand.

    If you want to go faster put different gears in your truck 373 is a good gear you should have 342 gears right now. Also buy you a custom handheald tuner and you will be well on your way to going faster. That is after you get a Cold Air Intake and a good aftermarket exhaust.

    My thoughts:

    3.73 gears - Around $2000 for parts and install
    CAI by K&N or AirAID - $220 - $299 (do it yourself)
    Throttlebody Spacer - $100 (do it yourself)
    Programmer - $299 - $499 (do it yourself)
    Exhaust - about $500 for parts and install

    These are Alaska I'm sure they are steep depending on where you sling your mud at.

    You do that and your gonna be quite pleased especially if you are running stock tires and haven't lifted it. I have all off the same mods on my 5.3L (except 4.56 gears and lift/tires) and I am COMPLETELY pleased at my performance.

    Where are you getting 2 grand for parts and install. I just got quoted at 300.00 for the swap in my 08 silverado. I couldnt even see it costing that much if you bought the whole axle. That is parts and labor. It is only about 1.5 hrs to swap the gears out. Then if you dont have a tuner you have to purchase that to swap your gear ratio on you pcm.

    Start out with an intake and exhuast, I'd recommend Volant intake and Gibson exhaust because that's what I have, but the choice is up to you, that will set you back about $700-$800 after that maybe a programmer another $300-$400 and then after that you're going to have to spend some real money! :great:

    You need a programmer that will disable GM's torque management. That will give you better take offs. The tuner will also help with a wee bit more horsepower. CAI and exhaust will help it all breath better and get you moving faster. If you get ambitious then I would mess with a new camshaft (~ $300 - $400), if your not familiar with engines have some else install the cam. Modding a vehicle is a true adventure, doing the work yourself wherever you can will save you big and gives that sense of accomplishment. Plus you know how it went together if there ever is an issue you'll know where to lokk for problems.
