    Range AFM Disable

    I get nothing from this. Zero, nada. I'm not even a fan of the Range AFM disabler, but for anyone who had been thinking about getting one, passing on the information, Woot.com has a one day sale (via Amazon) on them today...

    Mass Airflow Readings

    Anyone out there have any information regarding what kind of mass airflow reading (in g/sec) you should be seeing at WOT? I know that it will be relative to RPM as logically as RPM's increase, so does the air demand of the engine, thus the g/sec being pulled through the MAF sensor should...

    WOT isn't WOT.....

    An oddity I recently stumbled upon with my '08 Yukon Denali... I've verified this using two different scan tools. When I have the pedal pushed all the way to the floor, as far as I can push it, I'm only seeing about 83% throttle. I made sure the floor mat or anything wasn't obstructing the...

    Upstream vs Downstream O2 Sensors

    Ok, so, my understanding is that the downstreams are for the most part there to measure the effectiveness of the emissions control components and that the upstreams are primarily the values used for drive-ability, air/fuel management. Where I'm going with this is as I gradually work through...

    Lube Slip Yoke - AWD

    Ok...so I've read, and read, searched, and searched, and I'm still not clear on the topic fully. I know that all the late model GM SUV/trucks have a slip yoke on the front of the driveshaft, and over time/miles it gets to where it doesn't slip so well and results in a bit of a drive line clunk...

    Active vs Passive Suspension

    As I understand it, with the Z55 option you have active/adaptive suspension (electronically controlled shocks front/rear) and then auto load leveling airshocks on the rear. Whenever you're ready to replace/refresh your suspension your options are... 1. Keep all factory style function 2. Switch...

    Denali Airbag/Steering Wheel Emblem

    Anyone know of a source to get a Denali emblem for the center of the steering wheel? I know GM doesn't sell these by themselves, but they can be replaced by removing the airbag. I can find ones that just say GMC, or SS, or are bowties, but so far haven't found anywhere selling ones that say...

    Side Mirror Tilt Issue

    I thought I had seen this discussed somewhere before, maybe not on this exact forum, but so far my Google skills have failed me. I have a small nagging issue with the tilt feature on the side mirrors on my '08 Yukon Denali. Mirrors adjust, move and function fine, both tilt down fine when...

    Yukon Denali 1-2" Rear Drop

    Eventually I'll go with NORCAL SS's 2/3-4 drop kit (including doing the free-travel mod)....but, for now as a cheaper/easier/quicker option I'm considering just getting rid of the factory rake. That said, what are my options for doing so? I'm guessing a 1-2" drop spring in the rear. I've read...

    Remote Start "Mode" While Running?

    To begin, I'm about 99% sure nothing like this exists, maybe legal/liability reasons, or just not enough demand. So, as most of us are aware, when you initiate a remote start cycle, the vehicle will of course start, then enter a state where all the doors are locked, the engine is running...

    2008 Yukon Denali EVAP System Lines

    I'm having the common slow to fill the fuel tank problem on my recently purchased '08 Yukon Denali, likely caused by the previous owner(s) regularly overfilling the tank. I'm going to be replacing the EVAP canister soon, and although the recommended practice is to use some compressed air to blow...

    Another Exhaust Manifold Clap Install

    So, the '08 Yukon Denali I recently picked up had a broken manifold bolt on the driver's rear. I ordered a Kral KAP169 clamp and installed it today after work. From most of the threads I had read, there seemed to be a few different approaches to how best to do it. Ultimately what worked best...

    Upgraded VCIM OnStar Activation?

    I've searched, and read most (if not all) of the threads, and thus far been unable to really find an answer. Earlier this week I swapped a 2010 VCIM out of a Yukon (part # 20829984) into my '08 Yukon Denali. Swap went well, no problems pairing my phone via Bluetooth, all that works. If I...

    Fender Brace Bolt PN?

    So, my Google & searching skills have failed me so far. My new to me '08 Denali is missing one of the fender brace bolts on the passenger side up at the cowl. I can't seem to find a part number for this bolt, and it isn't illustrated on any of the exploded parts diagrams I've been able to...
