    2010 Denali/Mileage Question

    It's you, not the machine. First (if you're not heavy footed), the brake pedal is NOT the pedal drivers should use to control their speed - it's the WRONG petal. If I were following you, would I see your brake lights constantly flashing? Not only is this an attribute of poor drivers, it kills...

    '07 LTZ Upgrade gage cluster?

    My '07 LTZ is gorgeous and I've done some upgrades so that I intend to keep her. I've looked for a replacement instrument cluster that looks/performs up-to-date and can't seem to find one. I'd like a digital cluster that could display most/all of my truck's info. Can anyone point the way for me?

    My 2007 LTZ added second aux battery w/ pics

    The Aux Batt negative cable connects to the alternator mounting bracket and the I ran another negative cable to the factory installed negative cable bolt on the front of the block (passenger side) which is where the factory Main battery cable (with the factory DC amp sensor) is connected. So...

    My 2007 LTZ added second aux battery w/ pics

    Here's what I did with my 2007 (Cherry) LTZ. I wanted to power a dash cam that would not kill the batt when parked at the airport for weeks. I incorporated a 'Big 3' upgrade along with adding a second, new Aux Batt. 1 - Because I wanted to keep the batts disconnected when parked (so that BOTH...

    2007 Tahoe LTZ w/mod'd engine, Diablo I3 tuner question?

    Last week I got my Tahoe back from engine builder - cam'd, head work, AFM/DOD delete, overbore, etc. When I went to pick it up the 1-2 shift was VERY hard, and I had them take it back to dyno-tuner. However, he went too far and not she shift's sluggishly in all gears. I uploaded the...

    Rebuilt 5.3, what oil should I use?

    I just got my baby back from a local Charlotte engine builder with spec'd cam, overbore, headwork, dyno-tune, etc. When I asked the builder what oil he'd recommend with my new engine he said to use Conventional oil, 1030W. Hmmmm.... Do any of you have reason to choose something different?

    What size wheel/tire combo?

    My 2007 Tahoe LTZ is in a local Charlotte NASCAR engine builder's shop getting engine rebuild/mods, she gets dyno'd this week. She's not had lift modified so I actually have 2 questions - 1) I'm at original lift height with P275/55R20's so what's max wheel tire combo I can safely run? 2) I'm...

    Retrofit control app to 2007 Tahoe LTZ?

    I'm looking into how I could possibly retrofit a control app (like MyChevrolet perhaps) so that I could lock, start/stop, etc. with my Iphone. I do have a recent stereo upgrade. As I can't find anything on the InterGoogle about this, it may not be possible. Any of you been able to do this?

    Your thoughts/opinion would be very appreciated - engine ?

    I have an absolutely cherry 2007 LTZ with VIN Police Package. She has about 150,000 and I was lucky enough to tune out AFM/DOD not long after I purchased her. She has great oil pressure and runs strong. However, she had a catastrophic failure of a heater hose connection and overheated last...

    Diablo i3 Platinum - AFM disable - really working?

    I have a Diablo tuner on my ‘hoe and it have NEVER been in 4 or 6 cylinder activation since I deleted AFM (or DOD if you prefer). Your guy is wrong.

    2007 LTZ - No turn sig sound, no rear prox sound, no seat memory

    Recently I noticed that I have no turn signal sound (no audio click) though the signal lights work, no back-up proximity alert sound, and my seat memory won't 'save' (no 'beep beep'). (I noticed this about a month after replacing my stereo with a Best Buy aftermarket stereo with harness.) I...
