I'm looking to do some upgrades to my 07 silverado 4.8. I'm wanting to do exhaust, air intake, and possibly a programmer. Which brands actually give the results they claim? Also what kind of outcome should I expect from these mods? Thanks for any advice.

Your wallet will be lighter.

Seriously, sell the truck, add the money you would have spent in mods and get something with a bigger engine.

+1 on selling your truck.

none

air intake = plus 1 mpg highway
exhaust = nothing but sound.
programmer = nothing until you hit 4500 rpm

Let's see, you're considering "upgrading" that 4.8... I'm running a 2006 with the 4.8 and tow package. Here's my numbers.... towing an average of 20,000 miles a year (except last year, it was slow so I was down to 16,000 for the year), a small rig total weight less than 2,000 going down the road. In the 120,000 miles I've been working the truck, here's the maintenance it's needed.... At 119,000 the front brakes were replaced (just pads and turned the rotor), the rear brakes still have 40% left - I'll do them next year. Decided to get a full tuneup, pollution gear etc, found that the spark plugs showed almost no wear and no fouling.... and that was it at 118,000....

Since every day that I guide I log 200 miles round trip, tell me again why anyone would "upgrade".... The bottom line for me is that I can't believe how well my work truck (no options other than a/c and tow package) has performed these past 5 1/2 years and how trouble and maintenance free it's been. I'll be buying another when I can.

Well I wish my luck was as good as good as yours. Had to chan
ge brake pads and rotors at 55,000, transmission had to be replaced at 67,000, and the fuel mileage sucks. I average 16 mpg on the highway. The only reason I'm thinking about "upgrading" is because its upside down due to mileag e. My bay boat too heavy for it but it pulls a trailer like crap. I thought it may have been the trailer set-up but when I pull it with my wifes tahoe or my buddys truck it pulls perfect. That being said this will be my last Chevy I'd just like to get a couple more years out of it, but if there isn't something I can do to help it out it'll be getting traded in soon!

"air intake" on an injected engine is worthless..in fact, even a dirty filter won't affect fuel mileage. It's impossible. The O2 controls the mixture. All it will do is drop the total airflow, and the power at full throttle.

I did the mods you mentioned and you will get some seat of the pants improvement, but not worth the money I put in it. As far as programmers, go with the efi live. I went through three different programmers before I went to efi live. Like others here have said,SELL it and get something with some balls.jmo:thumbsup:
