2007 Tahoe Horsepower or lack of...

Just bought a new '07 LTZ model (5.3). Great body style, interior and ride...but no power . In fact, it seems to be very flat on the bottom unless you stomp on it, then of course your gas mileage goes in the toilet. I'm toying with chipping it, new exhaust and air cleaner. It's going to run about $1000. Wondering if it's worth it. Any comments or experience? Thanks

Backing out of my driveway this morning, I tore the rubber piece mounted below the front bumper off.. I really have to know.. Who came up with the need for this piece and did they ever expect it to survive winter?? I give up.

I agree, worst wiper blade (in snow/ice) I have ever used. ¼ in of snow, they turn in to a broom handle. Then if you try to lean out the drivers window and snap them, they fall off. As you know I also contacted Valeo and got the same story, no relief in site. If you look at their Web site, you can see that they went through several variations of the mount, until they found this one. The engineer that I spoke to stated that they have tested these in all weather conditions ! #$%^ and that they use same mount and blade on high end imports, yea that nobody drives in the snow. GM turned a work horse into a soccer moms ride. I also would have never purchased the 07 if I had the foresight to investigate the wiper blades. How that I have vented, here is what I have tried. (1) tried a set of 05 wiper arms, they did not work, wrong angle, etc. (2) tried to simply remove the rubber edge to see if I could replace it with silicone – no luck. (next) I am going to purchase a spare set of OEM blades at $30 each, drill out the rivet, and attach it to a set of quality winter blades. I have taken the measurements, and it looks like it will work if the rivet will come out with out damaging the mount. If it works I will post it here, I live 30 minuets south of you in Guilderland and experience similar weather/driving conditions. George

What's the rear axle ratio? Might have high gears in it for better fuel economy. 4:10 gears would make a big difference in the performance. Check the axle ratio and if it has high gears in it, it may be cheaper than $1000 to swap gears.

If you want to go from a lower number (higher gear) to a 4.10 plan on approx. $1000 for 2x4 and $2000 for 4x4 to change out the gear sets. I have the 4.10's and they are MUCH better than the 3.73's off the line but its still DOG! I wish I had paid the extra $1000 for the 6.0L
I am thinking about getting a new PCM for my 5.3L. Many appear to be happy with the programmed PCM from wait4meperformance dot com Very inexpensive for the results some are posting.

That sounds simpler than what I thought about doing, cutting the end on a normal wiper arm and welding it on the new Tahoe arm.
Are you talking about the silver/gray pin that holds the attachment thingy to the blade?
I was thinking that after I get a new set, trying to press the pin out and attaching it to a set of normal blades. There are several blades out now that have the same configuration as the Valeo but with standard attachment.
My parts guy will sell them to me for $20 ea. Not bad for a $5 blade.

Loss of Radio, Navigation and Onstar Service

I have a 2007 Tahoe LTZ with 9,700 miles. The following incident occurred on Friday - no explanation from dealer was available. I had been driving about 10 minutes, using radio and Nav system. I stopped at a local store for about 10 minutes. Upon restarting, the radio, navigation system and onstar service was inoperable. I stopped the vehicle and restarted thinking it would all come back. No luck. Even the turn signal "click" was silent. The heat and air controls worked as well as all the gauges on the dash. I drove directly to the Chevy dealer and explained the problem. Made an appointment for the next day to have them "Check it out". Upon starting my truck in the dealer lot all of the things that stopped working suddenly started OK. Did anyone have a similar situation happen to them? Dealer tested for "trouble code" but the restart clear memory. What was the resolution? Thx

Yes the silver p[in, however it is actually a rivet. I drilled one, and I have it a part. It is too wide for the standard ANCO blade. I have some more work to do, I will get back to you.

YES, I have the same problem all the time. GM is going to replace the BCM (Body Control Mod.) Every modual in the Tahoe gets a serial wake up/handshake signal from the BCM every time you start the truck. You should have set several codes that GM can read when you take your truck in for service. If you had shut the Tahoe off, and opened the driver door prior to trying to trying to re-start, the retained battery relay would have reset and everything would have been working again. I found that just re-starting will not reset the mod's you have to open the driver door or wait for it to time out (20 min). Good luck at your dealer, mine thought I was nuts the first several trips in. Then, like you I drove in to the dealers garage with several things not working, however I refused to turn the Tahoe off until they witnessed the issue first hand. hope that helps, George.
