My BIL used one on his 08 Chevy 6.0 2500HD. He did get a little more power but had to use premium gas.

Chips make no sense for non turbo engine. I researched this topic for my vehicle and found only one, with ability to boost power and torque by only 5%. They usually provide increase by eating into safety margins left by the manufacturer and will void warranty. No miracles here.

I ordered a new F150 SuperCrew Lariat 5.4 in 2008. The kid in me (at 35), wanted a little better performance. I installed Banks Monster exhaust and an Air-Raid intake. Wanted to install an Edge tuner but didn't get around to it. Around town, the truck sounded great...
Nice "big-block" rumble to it. We then purchased a small Excel 5th wheel. After our first pull it was apparent I'd grown up, and loud exhaust was no longer cool. What was upsetting is I saw no performance or fuel mileage gains from these modifications. I don't know if a chip would have helped or not. A friend has the parts now. The Banks exhaust came off after the first trip, and the other parts were removed after the second trip when I traded for the F350 diesel.

In terms of maximum fuel economy, competitive horsepower/torque and performance vs reliability, the manufacturer's engineering department in all automotive companies, have pretty well tuned the modern internal combustion engine to it's best performance while maintaining the reliability necessary to keep it out of the repair shop as long as possible. If they didn't, buyers would move to the competition in "droves." All the engineering done on today's cars and trucks is aimed at maximizing performance while maintaining reliability well past the warranty expiration. Otherwise they couldn't sell their products.

Diesels have still got some "improvement" capability by tweeking the fuel and air flow, but in gas engines, pushing the limit (with performance chips) for the minimal gains that can be achieved while reducing reliability isn't an "even trade" any more.

Gone are the days of replacing a quad barrel carb with a new manifold and 3 "deuces" and having the "hottest rod" for Saturday night.....

Thankfully it's not "plugs, points, condensers and a rebuild" before 100K. My grandfather owned an independent garage from 1938-66 when that was commonplace. Thanks to fuel injection and other modern advances, engines last so much longer than they used to! I was really disappointed in the results after modding mine. I was oping for alittle better fuel mileage. A friend of mine has all my parts on his truck now. The exhaust came off after the first pull with the 5th wheel, (didn't take long to get tired of listening to the exhaust resonate off the trailer as the engine's turning 3K!) and the intake was removed after we came home from the second trip and traded for the F350 Diesel. I really liked the F150 as I special ordered it and it only had 16K on it in 2011 when I let it go. We knew we'd upgrade coaches and wanted plenty of truck when we did. I'd like to do a DPF delete and tuner on the diesel to improve the mileage, but after wasting money on parts that "claimed" to make a difference, I'm hesitant to waste money again. I only drive it about 5K a year, so I might not ever recoup my investment, but I'm sure it'd make it more fun to drive! I'd say there probably isn't any "real" advantage to chips, intakes, or cat back exhausts on a modern gas truck.

Contrary to several of the negitive post I personally have had good luck with the mods I have done and the chips I have used in my gas trucks. On one of my trucks I used a Hypertech chip along with exhaust, intake and ignition upgrades and increased my fuel economy by about 3 gpm and the added power made pulling much easier. As for doing the upgrades and it taking life away from the truck, personally I never seen any of that. I had well over 250,000 miles on this truck when I got rid of it and it never burned a drop of oil and still ran great. I've seen new vehicals die with less miles and no mods! It's all in how you take care of it. If you drive it like you stole it then it's not going to last you moded or not.
This is just my own experiences and I would do them again. I'm currently doing mods to our Duramax which include several of the same mods I've done on my gas trucks.

I think i will start with a cold air intake to help performance on my 454 chev.

tdawg,

If you're modifying a 454, IIRC, it was last used in GM trucks about '99 or '00. That was long before the modern mandates for fuel/air control for the current emissions standards. You may see a little improvement in those model year trucks, but if you try to put a cold air intake on a current model truck, it won't work unless you reflash the computer to compensate for the MAP settings.

I wouldn't say your mileage is that bad now for what your pulling. Our '09 F350 Diesel gets 8-9mpg pulling less trailer. We gross a little over 17K with 8,700 of that being the truck.

Chips on gas trucks in my experience inherently make their gains at max hp and max rpm(where you seldom drive in the real world). They do this with the requirement of premium gas so they can run more timing.

One other thing they do is fool the onboard mileage calculator, so that unless you actually figure fuel used per miles driven by hand, the readout will tell you feel good story.

A less restrictive exhaust on a gas truck that is pulling HARD will help it run cooler to a certain extent, (not less restrictive does not necessarily mean louder) or at least don't have tailpipe pointing at the trailer.
