Replying to: nosbor77 (Jul 09, 2006 10:15 pm) Not really. I've only been driving the new Av for about three days, put over 100 additional miles on it (had 5 to start with). The average MPG display keeps climbing a little bit at a time, despite my "break in" driving routine (basically keep off the interstate as much as possible, side roads w/lights n stop signs, varying speed limits between 20 and 55ish, etc.). Right now it has worked its way up to 15.7 from a start at roughly 6. I fully expect it to be 17+ on the display by the time I fill it up, and probably really close to dead on 16 when I calculate it manually.   Once I finish the 500 mile break in period I bet it exceeds to 20 highway estimate. But I usually exceed my EPA numbers, due to my driving style and conditions. Why am I telling you this- mileage results are HIGHLY driver dependent. If you aren't getting EPA numbers in your Tahoe, there's a very strong chance you wouldn't in any other vehicle either, unless something is actually wrong with your vehicle (and you'd have had other concerns ahead of the mileage then).   I'd love to elaborate on what kind of driving it takes to get better mileage, but it's really hard to say. Easier takeoffs, keep RPMs below 2000 where you can, keep speeds high enough to get into top gear with the torque converter locking up, minimize the amount of pressure you put on the throttle once there to what's needed to maintain that condition, anticipate stops and starts, minimize speed changes.. could go on and on. Everyone drives differently, and all driving conditions vary. So results do too.   The numbers on that sticker are the results of EPA "similated" city / highway test loops, standard for vehicles across the board (same route, speeds, stops, etc.), so you can't really expect them to exactly match your own results. All you can make of them is that vehicle 'A' will do better or worse than vehicle 'B' in the conditions they tested under (meaning likely the same relationship for your results from 'A' to 'B', even if the numbers don't match directly).

Replying to: cecook (Jul 10, 2006 5:05 am) I'd be interested in hearing the results of this myself. I held off adding the door handles to my up-front mods to see what experiences others have. I really want to avoid messing up the interior door trim when replacing my handles, but the last thing I've seen online indicates that the interior door panels have to be removed to change out the handles. That's good because it means the handles are REALLY chrome handles, rather than just stick-on appliques. But that's bad because it means there's lots of potential to break a fastener or incorrectly reinstall something in the process.   I'll let someone else work out the correct procedure and the "gotchas" before I do the job myself.
#1340 of 3125 MPG by 07denali Jul 10, 2006 (8:13 am)
Didn't anyone test check the computer during the test drive before they bought to see the MPG it was getting? My Denali XL gets about 7-8 MPG city and 16-17 MPG highway. Am I surprised, no I looked checked the computer before I purchased and saw I averaged 7mpg during my test drive. Replies to this message: nosbor77 (Jul 13, 2006 9:22 am)
#1341 of 3125 Tahoe leveling kit by junglegeorge Jul 10, 2006 (11:53 am)
Does anyone have the scoop on this newly released 2 inch leveling kit? JUST RELEASED !! This is the first leveling kit for the 2007 Chevy Tahoe / Suburban 4x4. Works with autoride option as well. This kit raises the front of the vehicle 2". It is very easy to install and is backed by a lifetime warranty. Made from billet aluminum and the best hardware. Will not rust or corrode. This kit is made by Skyjacker and brought to you by Top Gun Customz (an authorized national distributor). This kit is very easy to install and does NOT require compressing the coilover for installation. It WILL maintain the factory ride of these vehicles unlike other leveling kits which install IN the coilover. This one installs on top of the coilover.   Maximum recommended tire\wheel size 285/70/17 with OEM/stock backspacing     George

Replying to: 2tahoes (Jul 08, 2006 3:44 pm) Reset the computer and start over again. The instruction manual tells you how to do this. I am regularly getting 17 to 18.4 MPG in mixed driving. If you zero out the computer and then do mainly stop and go driving, you should expect much less mileage than if you average it with highway driving as well. Mine now has 9,000 miles; the best I ever got was 22 MPG from Vermont to NJ.

It's interesting to see everyone's posts regarding their MPG situations. I really appreciate the posts. While I was so excited to hear that the 07's where supposed to be so good and then be a little dissappoined, I wouldn't trade mine for any foreign job. So much to love compared to my 01 tahoe. Still can't figure out what GM was thinking when they show (on their web site and in their brochures) all these great after market goodys that still aren't available!

Replying to: cecook (Jul 10, 2006 5:05 am) Nope. Did put in billet grill tho. Thinking about the GM perf. or touring exhaust. There was someone who was talking about chrome door handles in this forum.

Replying to: nosbor77 (Jul 09, 2006 10:15 pm) I remember seeing on this forum or some other online forum that to get the best mileage, you should drive such that you never have to brake above 40 mph. Of course this excludes emergencies. I think the point was is to look ahead and anticipate what traffic and signal lites are doing so that you can let up early if needed (without blocking someone behind you like Matt Kenseth did yesterday at Chicagoland to Jeff Gordon). I know this is hard to do especially if you like the sound of the induction noise (I do) when you get on it. Was really surprised that it is that loud with all of the resonance chambers they use. Kind of like when we use to turn the air cleaner cover upside down. That probably dates me.

Replying to: 2tahoes (Jul 10, 2006 7:51 pm) I've got an '07 Escalade running the 403hp, 6sp tranny. At 5000 miles, I'm averaging 15.2 combined.   Pure highway, minding a 65mph max, I get 19 (flat road). In the hills here in Tahoe, about 16.5.   Pure round-town with no more than 45mph, and no more than 1/2 mile between stop signs or round-abouts, about 10.5.   Dave
