Have a great day,

I should try a CAI on my 07...been getting constant 17.5-18.5 MPG...maybe i can step over to the 20mpg with a CAI

I'd be happy with 17 ,, I am getting 14.7 city

Well see everyone lies about MPG on here because they want to feel special. I get 13.5 city and 17 highway and when it didnt have as many miles on it it got like 14.7 city and 19 highway. A cold air intake wont change mpg by 1.5 mpg, but you can believe what you want. All the mods (exhaust, tune, intake) get you worse mpg at least in my truck because I always get on it to hear everything work.

It will because he just replaced the air filter. 2000 miles down the road the milage should be about the same again.

TheHun · September 17, 2007

the way i calculate mpg is i reset my trip computer, and whenever i fill up i take how much it took to fill it up then take that number and divide what you got on your trip.

Say I am at 150 miles and i want to fill up (taking you completely filled up last time and reset trip) and you filled it up 9 gallons....you got 16.7mpg

You have absolutely no faith in your fellow man/truck owner...at least you're honest about your mpg.

I have only an S&B drop in filter and an AIRAID intake tube installed. I'm averaging just under 17 mpg in my '07 Silverado crew cab, 2wd, 6.0L...in mostly around town (@ 5,200 ft altitude) with 1,550 miles on it.

I clear everything on the DIC with every fill up. I was amazed last weekend that I got almost 19 mpg during a weekend drive on a serious twisty mountain road trip of just over 125 miles to as high as 7,000 ft altitude. It's a brick.

I do feel special!

Well, let me join the liar's club as well! I'm getting a pretty consistant 18.5 mpg on my daily commute that consists of a 32 mile round trip of 50/50 city/hwy! I get between 11-12 mpg towing my travel trailer on the open road...

I just added the GMPP CAI this weekend, so I really haven't had a tank of gas through it yet, but I really don't see a difference in my daily commute MPG yet. I did notice a significant difference getting on the highway pulling my new Travel Trailer that weighs about 2000 lbs more than my last one, it actually felt like it accelerated faster (relatively speaking) than it did with my last trailer! Maybe it just sounded faster with the really cool growl of the new intake!

Will my mileage actually increase, that remains to be seen! In theory, it shouldn't! The principle of a freer flowing intake is to draw more air into the engine. The computer works to maintain a preset fuel/air mixture, so one would think more air would mean more fuel and a result of less MPG! This, of course is limited to the physical capacity of the cylinders (they don't expand like a balloon with more air)!

But, the arguement that persists is that a freer flowing intake makes for a more effecient engine, and a more effecient engine should result in better fuel economy! I guess because it really doesn't have to suck as hard to fill the fixed capacity of those non-flexing steel cylinders!

I'm no friggin engineer, so who knows what really happens! I do know it pulls my new (heavier) trailer as good or better than it did the old one, so from that perspective, I'm happy!

Paul, glad to hear you had good results pulling your trailer. I'm very interesting to see how mine does towing next weekend, as this will be my first trip with the GMPP intake.

No im not talking about people like you. Im talking about the people who say they get over 20 mpg in the city with like a 6.0L V8 and 4x4. No way. Not unless someone pushes them. 18mpg on a commute is pretty good and about average for a new truck. Im not calling everyone a liar, im just talking about when I look through the average MPG thread i have to laugh.

omegafiler · September 18, 2007

I bet I could get 20mpg,

...if I put it in Neutral, going downhill, going in the direction of the wind, with somebody pushing.

ujtruck · September 18, 2007

Everything still stock - I am getting 17.5 on HWY - I am happy about it...

but installing one of those CAI will not make your MPG better - unless you remove your throtal plate.

Gozer,

It certainly felt better getting on the on-ramp! Don't know what effect, if any, it'll have on my gas mileage, but it sure sounded gooood! Let me know what you think after you've had it on the road with your TT! Unfortunately, I recieved and installed the GMPP between trading my old TT and picking up the new one, so I can only compare old to new, I can't compare the difference with the same TT as you can! Here's a picture of the new one:

People still tend to confuse the unmuffled sound of incoming air with more horsepower/torque (I like the sound, too!)...same thing with a louder exhaust. If it's louder, it must be producing more power...

Very few manufacturers can actually substantiate their claims of power increases. Even if they have dyno results for proof, look at the rpm levels required to achieve the results.
