If this is true, I think you have a serious problem. I am getting 13 - 14 around town in mine. 2000 K2500 3.73/6.0 litre 265/75/16 tires.

Thanks
Yes the tires are the 265's and the gearing is 4.10. As for the power issue I am now wondering if one of the engine's main problems aside from the computer program is the camshaft. I'll bet that GM has a stick that would really give it some low end pull but the consumer will never be able go get one. An idea that warrents futher research but where do you go. Any ideas welcome!!
Also about the tire change I had to go to the hypertech programmer to make the change.
Sublimital,
The best milage I have gotten in town not towing was 10mpg and the best on the road not towing was 13.5.
If you have the Hypertech, you might consider moving up to a 4.3 or ? rear end. Cheapest way to increase torque to the rubber. I think that the 265s are a very good idea if you are towing a lot. Margin is always valuable.
We have had a few problems in 17,000 miles: Two dead window motors, bad relay for rear A/C (first dealer said there was no rear A/C with a factory sunroof - insisted the sunroof was aftermarket!), and two problems that it is going in for on Friday. First, the "security" message lights up in the message center frequently, often while driving. The second problem is that it sometimes fails to start, although it turns over fine. I wait ten minutes and it fires right up, almost like it is flooded. It is the 5.3 motor, which has been awesome other than that. Any ideas on the security message or failure to start? Thanks either way!

No thoughts on the security light but the no start thing sounds like what happened to my Bonneville a while back. Have them check the Crankshaft Position Sensor. Do you have any problems with it while driving (cutting out, running rough, etc.)? That's what was going on with my Bonne and the dealer gave me the standard "cannot duplicate" every time I dropped it off (even had it towed in once but of course, it started right up and it never set a DTC in the computer.) The only way they found it was I told them to keep the car until they fixed it and they put a real-time scanner on it and drove the car. It finally happened while they were driving it and found out it was the crank sensor.
Hope that helps.

I've tried the new Meguiar's Scratch Remover in the black tube... no good... I know they used to make a 'Swirl remover' product.. not anymore...
any comments are appreciated..
thanx
I also wanted to thank Ryan for pointing me in the right direction on the "Odds and Ends" problems I am having with my Y2K YXL. I am pretty sure it is the PassLock system coupled with a bad ignition cluster from what I have read. This would cause both the "security" message and the occasional failure to start. Campo, I appreciate your thoughts and have shared that problem before. I had two '87 Grand Nationals and they BOTH had bad crankshaft sensors. One tended to leave me stranded until the dealer figured it out on the fourth try. The second car was fixed the first time it happened, of course. Thanks again for the help!

PS. I haven't seen a thread on mileage for the 5.3, but I am VERY happy with mine: Roughly 15 mpg in the city and 19 mpg on the highway. Compared to my '93 with 12/16 and much less power (5.7), we are thrilled. Try a Dodge Durango that gets 11/14 - THAT stinks!
also re: gas mileage .. my '99 ( WHITE and easy to keep clean ) Subn LT 4wd 5.7L gets 15+mpg around town and 'mixed' driving and 17-18 over the road Interstate driving with 44K miles on it.. so far her new '01 Subn 5.3L gets 15+mpg mixed driving around town and 18 on a couple short trips of 100+ miles from Myrtle Beach to Charleston SC on Rt 17...
gpvs I just found the Griots Garage site.. will check out their car care products.. thanx... http://www.griotsgarage.com/index.jsp

Does anybody know of any incentive coming in June? I do currently own a '95, and want to use the loyalty rebate while I still can.

Looking to put 285/70/16's in place of firestones. Tire dealers are scared thesed days to suggest alternate sizes. Anybody have experience with this size.
I am also looking to put on the wheel flares from the 2500 on the 1500. These are quite subtle and not as large as bushwackers. Any comments from would be appreciated.

for pics of my husky floor mats. They are awesome. Hold mud snow water very good. Just wipe em with a damp towel to clean em.
Z71 PKG someone mentioned their burbs going somewhere in indiana to be "customized" with the roof racks and such. Well friday afternoon i drove by the place that does them while on my way to ohio. They had about 3 dozen burbs in their back lot. Most of them were black. They had a few that were done and ready to ship. So if your waiting they are on their way.
