Snow,
Hope the winter has been good to you so far. How about an update on your 05 Silverado. I am very interested in a new crewcab truck for hunting and traveling. My old truck is a 2000 3/4ton crewcab LS with the vortec 454. I love the way the truck runs and rides but the 12-14mpg with a 26gal fuel tank means lots of stops on a trip. How has the 5300 held up for you and what kind of gas milage are you getting? Did you ever put a different tuning program in the truck?
thanks, jaeger

JAEGER; I had a 03 heavy half crew with 6.0 that was thirsty all the time. I now have 05 crew with the 5.3 and love it. the 5.3 will eat the shorts out of the 6.0. i average 14 to 15 at 75 mph. if you have the time to drive 60 to 65 it will pull 19 to 20. i hooked a 28 ft camper on back when it was new and it pulled it fine without pulling its guts out but the mileage was only 6 mpg with a mild wind behind me. the truck was new then and now that it is broke in at 20,000 it pulls the camper and averages 10 to 11. I can't say enough about the 5.3 as it is a whole different truck than my 03 was.The only complaint is that I bought 1 year ago and can go buy now for $5000.00 less than what I paid back then. Makes you feel good when you get that monthly statemant for $683.00 and you still owe $31,000 on a truck that you can go out and buy now for $27,900. THANK YOU GM FOR MAKING THE WHOLE COUNTRY A GOODWRENCH EMPLOYEE.

Thanks Flagger,
That's pretty much what I've heard from the folks that have the new 5300 Silverado. Did you ever try to reprogram yours? What size tires do you run and what ratio gears did you get with the truck? I've heard there is a lot of difference in the performance between the .410 and .373.

p.s. If you ever need a gun rack for your crew cab check out Cabellas, they have one that connects behind the front bucket seats and holds three long guns for $35.

Jeager,

New toy for xmas? same as the 05 I had the 06 is sweet,5300 v-8 and running 3:42gears.The GVW of the 1/2crew is 600lbs heavier(7000) than the 1/2e-cabs(6400) I normally run so I did notice a slight drop in mpg's.I'm running the new Hypertech3 in it on stage 2,extra 77hp is noticable and getting 16+ alot of which is city driving right now,also have a soft tonneau cover which helps minumize tailgate drag and also helps the mpg's.Did'nt change the tires either,I like the stock Bridgestone dullers 17"265's,quiet and good traction.

Hope all is well,

Later,

Snow

That 3:42 rear end isn't going to be worth a crap if your pulling anything consistently.

Why would you say that?,pulls just fine...remember the stock motor puts out 295hp and 335 net torq and not that I need the extra 77hp/torq with the chip,370hp is plenty to pull anything comfortably under 4000lb(even though the power train/truck is rated for 7k)

We're talking a 1/2 ton truck here,not a "stump puller" like a HD or 3500(1 ton)You can get get deeper gears if need be,3.42's are an option for folks like me that run around 80% of the time empty or hauling a small trailer,great gears for milage,lord know's we all need the savings at the pump.

Thats why I put the word consistently in there, if your only pulling once in awhile they will be fine.

Plus horsepower doesn't really mean much when it comes to pulling, its all about the torque.

Right,335ft pds(std) is plenty with the added hp and extra 60ft pds from the chip,its more than enough...

Snow,
Thanks for the update. Like you said in your note I'm looking for a truck to do my hunting and traveling, very little towing. Are there any other engine configurations I should consider? Do I give up fuel eficency if I add the off road package?
thanks, jaeger

jaeger,

In the crew model,the LM7 5300 is your only option,get the Z71 package,gives you "flares" 17"wheels and 50mm shocks and skid plates plus a package discount so bottom line(price)is the same as a regular 4x4.The trailer package gives you the locking diff,make sure you get it...(G80)You'll be happy with the factory tires,if not the go with the BF KO's(285's) you will lose mpg's(2mpg) using these meats but gain greater traction.

I just purchased a 05 chevy extended cab Z71 with the tow package and with the aluminim heads and aluminum block that gives you 310 hp compared to 295hp on the cast. It has 4:10 gears. You dont want the 3:42 because they will shift all the time in heavy wind and pulling up hills. In nice weather i average 17 to 18.8 mpg at 70 mph. In cold weather i can get 13 to 14.5mph at 70 mph. I have put 4500 miles on the pickup so far.

Are you dropping 4 mpg from letting it warm up or some other reason in cold weather?

You can't aim a duck to death.

I do let my vehicle warm up but its just the cold weather that takes away the gas milage. I was not counting warm up time. I have a 01 and a 03 and they both lose gas milage in winter also.

I just bought a 99 GMC 3/4 ton. It has Firestone 265/75s on it and the 6.0 liter. I am in Grand Forks so it has been around 0-20 degrees out when im driving. I have only put about 3 tanks of gas through it but have gotten about 11-11.5 mpg. It has been mostly highway miles or hunting miles (45-55 on gravel roads). I was just wondering if this seems about right to you guys for mileage, i expected to get more like 14ish mpg. Any input would be appreciated, thanks!

THE 6.0 IN MY 03 WAS ALWAYS 11 TO 12 ON THE HIGHWAY UNLESS YOU DROVE SLOW LIKE 55 TO 60. MY O5 HAS 3;42 REAR AND I WILL TELL YOU ONE THING IT PULLS A 28 FT CAMPER AT 3600 RPM'S AND HOLDS IT WITHOUT LUGGING THE ENGINE. I TRAVEL FOR WORK AND THE MILEAGE DIFFERENCE FROM THE 6.0 AND THE 5.3 WILL PAY FOR ITS SELF IN NO TIME. WE BETTER QUIT TALKING ABOUT MILEAGE AS THE ASS PUMPERS HERE IN JAMESTOWN WENT UP 10 CENTS TO 2.19. I DON'T HAVE ANY PROBLEM WITH DOWN SHIFTING IN WIND OR WHATEVER. I JUST PUT B.F. GOODRICH ALTERRAINES ON AND WILL BE CURIOUS WHAT HAPPENS VERSE THE BRIDGESTONES THAT CAME ON IT. I KNOW I WON'T GET STUCK UNLESS I INTENTIONALLY TRY TO. I WILL ADD THIS COLD AIR HAS EFFECTED MY #'S ALSO.

Alright, I have to call B.S. on some of this, yet some is dead on. I don't post all that often but do a lot of reading and spend a large amount of time on a simular web site for trucks & SUVs so when I see BS its hard to resist.

1st, you can not get 77hp or ftlbs of torque just by adding a chip to a n/a (naturally asperated) engine. Only turboed and Supercharged vehicles will see these gains. your 5.3L on the highest performance setting (which you have to run 91-93 octane inorder to keep perdetonation from occuring) will only produce 18hp and 16ftlbs of torque and on the performance 2 mode is only good for 11hp and 10 ftlbs, no where near 77, if the sales man told you 77 he lied to you so you would spend $450 on a programmer!!

2nd, all the power in the world does you no good if it's not in a usable RPM range. That 295-310hp and 335-350ftlbs (depending on what sereies) is rated at 5200rpms and 4000rpms, which last time I checked I do very little of my driving at these RPMs! generally going down the hwy at 70mp will give you around 2000rpms in OD and 2800 in D(give or take 10% depending on gearing); thats a far cry from 4000rpms and not even within shouting distance of 5200rpms. you actually have about half of that advertised hp and tq when driving if its not to the floor board!

The 3.42s will tow 4k alright and will tow 7k but I wouldn't make a habit of doing it everyweekend and not on extended trips. A few trips to the lake each year it can do but it'll be real thirsty and you'll be working the crap outa it just to maintain 60mph. Also you'll be putting a lot of stress on your drivetrain with those tall gears, see trany failors!!

The mileage on the 5.3L is rated at 14-18 town; and 18-21 hwy; but in order to get that 18-21 you'll be driving with a tailwind, pushing the go pedal like you have an egg under it, and driving at a respectable 65mph!!When the vehicles are EPA rated they are put on a chassis dyno and ran through a variety of rpms and speeds, but has neglected wind, temp, frictional resistance of the road, and all other "REAL WORLD" apsects. I also got near 16mpg with my V10 ONCE but I don't go bragging about it being my average since it took a 15mph tail wind, me driving very resonsibly (65mph), no jackrabbit starts and a straight through 400 hwy miles with only two stops. No, my hwy average is more around 12-13 with my in town being sligthly less at 10-12, sad thing is as some one already stated the 6.0L chevy is a terrible gas hog, why??? nobody seems to know but they all get crappy mileage. The point is the 5.3L is the most fuel effecient engine that has respectable power but 18-21 is kinda wishfull thinking when it comes to most peoples driving habits.

Lastly if you had a 454 and do any moderate towing you'll be very, and I mean very dissappointed with a 5.3L. The reason is your 454 will lug along at 2500rpms and tow 6-8k with out any reasonable problem, that 5.3 will be at 3500-4000rpms just to try and do the same job. Also the suspension under your 3/4 will flatout handle the load better than any half ton no matter how overflated the manufactureres seem to make the tow ratings. Good luck on you pruchace but don't buy into all the HYPE, because most of it is just that, nothing more than inflated numbers that have no real world application, and every manufacture does it. If you think I picking on GM I can prove you wrong when Ford rates the "NEW" F150 for 9900 GVWR and my superduty is only rated for 8800, you tell me which one you'd feel safer hauling 4000lbs of rock in............. thats what I thought. Dodge is no better but since Ford and GM seem to be in a pissing match over numbers I just thought someone should set the record straight!! Sorry for the long winded post

lund,

The 77hp(stage 2) (140hp stage 3) did'nt just appear,and i never listen to a salesman,I suggest you visit the Hypertech site and read it for yourself,and if it is smoke and mirrors the performance is noticable futher more GM has been tweaking their motors to get more hp and torq over the last few years because they can w/o over boring.Look at the Duramax 02-04 300hp,04-05 310hp,06 360,or how about the 6.0lit 300hp,last year 325hp and the hi-performance 6.0 is 390hp.Even the 5300,in 1999 the hp was 275hp,2000 to 2003 285hp,now 295hp and 310.My point is the "unharness'd power is there whether you want to believe the hype or not,we will see more on these programs I'm sure right or wrong its happening and folks reconize the benifit whether pulling a boat,5th wheel or skid steer I here the feedback and do not have any reason to doubt.

Lund, I agree 100% with your post. I owned a truck with the 3.42's and it was the biggest pouch I ever owned. As far as towing, get used to the tranny down shifting often. I now own a 3/4 ton with the 6 liter, and as stated earlier, it likes gas.

sorry, keep dreaming tim!! The diesels are the only ones that are able to increase power in significant gains and that is due to the forced induction (turbo). I've done the research and ran vehicles on the dyno, maybe you should invest in a custom tune and dyno run so you can quit posting B.S. By the way here are Hypertechs results of the 2005 5.3L HO (which is stated at the bottem of the page)

http://www.hypertech.com/get_dynochart.php?cid=85&vid=1431121&tp=jpg

Maybe you'd like to reverb you last statement of 77hp since I even had it wrong. Its only 12hp and 19ft lbs on the performance 1 tune and 6hp and 12ftlbs and performance 2 tune!! thats no where in the vacinity of 60ftlbs and 77 HP!!

oh, and by the way GM has been doing more than just computer tuning their vehicles, they've changed many internals, of course the tuning, the exhaust, the intake, the fuel injection, and the largeset gains have came from improved cylinder heads. power is never free, I asume you beleive the K&N adds and tornado adds also!!! Yes the diesels can gain hudge performance but the gassers arn't there yet and like I stated before diesel can do it because of the forced induction!! If you don't have a turbo or SuperCharger you aren't gonna see these huge gains.
