    BCM Programming

    I know EFI Live can do some changes through OZ Tuning but I think it’s a canned program. You can’t customize anything. I’ve got access to a Tech2 and MDI2 but I have no idea if you can change anything even with a GDS2 subscription without going through GM.

    BCM Programming

    I emailed them and they won’t disable any “safety features”.

    BCM Programming

    I've got a 2009 GMC Yukon Denali 2WD that I would like to make some modifications to the BCM. I'd like to disable the DRL, Traction Control and Stabilitrak, and a few other Mickey Mouse things that annoy me from the factory like the door chime. What I would like to know is if the BCM can be...

    Black Bear Tune Problems

    I'm having trouble with uploading my new tune files to my 2007 Tahoe. I received the file from Justin, downloaded them to my PC, then to my AutoCal. When I try uploading the file to my Tahoe, the AutoCal displays a message with error code 0533. I did an EFI Live update that was sent in...

    Leveling a 2014 PPV

    Another thing to consider is if you are trying to go lower than the stock PPV height, the driveshaft angles are going to be off. While it might not be an issue on a Tahoe at normal speeds and daily driving, it could very well cause some type of failure at sustained speeds of say 125-135 MPH. I...

    Leveling a 2014 PPV

    As far as I know, the Tahoe PPV only comes one way from the factory and there is no option from GM for different heights. I would assume what you've got is the SSV, which comes in 4WD or someone swapped out the suspension components. Although the SSV has some of the same features, it is...

    Aluminum vs Steel Lower Control Arms

    Sorry I might not have explained that very well...I don't have a PPV, I've got a Yukon Denali that I installed the PPV shocks and springs on. My stock ride height from the ground to fender lip was 37.75" rear and 36" in front. After I installed the PPV shocks and springs it is 36.25" rear and...

    Aluminum vs Steel Lower Control Arms

    Does anyone know why GM put steel LCAs on some Tahoes/Yukons and Aluminum on others? I recently converted my Denali to the PPV suspension (shocks and springs) expecting a 2" drop in the front and rear. It only dropped it .5" in the front and I'm wondering if that has something to do with the...

    Autoride Bypass

    I bought the Arnott conversion kit that comes with the bypass module. I got lucky and sold the set of bilstein shocks/ Arnott springs that came with the kit. They won't sell the module separately. It wires directly into the autoride module under the spare tire. When it's wired in, the...

    Autoride Bypass

    I've got the autoride system completely bypassed. Does anyone have any experience with the PPV suspension or should I look into something aftermarket for a 2/2 drop?

    service suspension system override

    I'm doing the same exact thing to my Denali. You're going to have to bypass the autoride system by wiring in resistors to each shock/strut wiring harness. From what I can tell, you need a 3.9ohm 20 watt resistor. You'll have to cut the harness off and wire each side of the resistor into the 2...

    Autoride Bypass

    Hello...I've got a 2009 GMC Yukon Denali 2WD. All 4 shocks need to be replaced and I would like to install conventional shocks/struts and lowering springs. I would like to go with a suspension system like what's on the PPV. I don't want to go too low, maybe a 2/2 drop with stiffer springs and...

    How can you tell shocks are 'worn' or bad?

    I'm no shock expert but most manufacturers recommend changing them every 50K.

    Swaybar Options

    Hello all... I've been lurking for a while, but obviously this is my first post. I have a 2001 Tahoe 2WD, 5.3, GU6 open rearend. I'm wanting to lower my Tahoe 1" in the front and about ~2" in the rear. I'm planning to used GM blue keys in the front, Z56 police springs in the rear and...
