    So I did something stupid this weekend.....

    Tom, The AWD does state it has 1 qt more for the oil pan capacity but I've found in my last several oil changes it takes about 6.5- 6.75 quarts to be at a full level. If I put in 6 quarts in my AWD ATS, it always show it's a quarter low on the dipstick every time. I'm kind of curious how hot...

    Compound turbo tuning

    The problem with the vane going to 0%, you start losing the valley charger boost and the atmospheric charger starts working harder, so you lose the overall boost. During driving, I would watch my boost climb to spike at 45-50 psi, atmospheric charger is pushing 35 psi then when the vane backs...

    So I did something stupid this weekend.....

    What made you go into the suspension, loose or noise? I can imagine the mess you're in, pretty much any car with the LTG are beat to death. I had the same situation when I was looking for a daily driver, ended up finding my 15' ATS with 18k miles owned by an old lady in damn near excellent...

    Compound turbo tuning

    Thanks Josh. I haven't been able to do much tuning lately due to the rain won't stop in New England, makes it harder to get an accurate reading at WOT. I've done a bunch of adjustments to the turbo vane in both minimum and maximum, also made adjustments to the desired boost. The code popping...

    Compound turbo tuning

    Thanks. Does this correct the issue for popping an over boost code? As I've read, I should be pushing 55-60 with my setup, can't get over 40. That's when it pops the code and backs off the boost to low 30s. I have my desired set around 40, wasn't sure if I can raise it higher without hurting the...

    Compound turbo tuning

    So as the title says, need some tips to get me dialed in on my LBZ. I've done countless research over the web and not much info to get me dialed in. Mostly related to vgt tables and map/boost settings. So far I've taken small changes in the tuning as I've progressed over each tunes I've done and...

    Front Differential Gear Whine on Deceleration - Yukon 4.56

    What gear oil are you using? Try changing gear oil brands any what type of weight are you running? In some cases, a lucas oil stabilizer can help with the whine. If those didn't work, then it's a gear issue. You may have to change the contact pattern a bit from the usual standard footprint...

    Intercooler mount/bushing

    What newer number does the truck come off from? I just happened to come across from another forum that LMM bushings fits the same as lbz. Is that what you were talking about trimming on?

    Intercooler mount/bushing

    I've been searching for a while but can't find the damn lower intercooler mount/bushing for my LBZ. Found a massive leak at the intercooler where the pins goes in at the bottom. I'm pretty sure they're shot and want to replace them before I put my new intercooler in. Any help would be...

    Oil cooling

    James, load em good. Every engines I built when I was at Empire, it gets thrown on the Dyno right after it's finished and loaded up to the max. Those were 2400hp diesel engines for the Morenci mine haul trucks. Most of them made it over 10k hours and those operators aren't easy on them. If you...

    That l5p cooler will definitely help your cooling issues in the hot summer days of towing. Pretty sure all the stuff you got is going to last you a while without issues.

    NP246/266 custom build

    The short bed boxed frame you mentioned, are you using a 2500hd shortened too short bed and box it or using a 1500 frame boxed up? I've always thought how cool it would be to have an AWD single cab short bed Duramax meant to handle the track or windy roads where I live. The suspension, would it...

    I don't know what the GM design team has been smoking but there's more disappointment to me in today's GM vehicles. The 1500 front end is meh. The 2500/3500 is fugly, looks like Ford's down syndrome brother. I do like the rest of the body and the interior, but come on, they can do a whole lot...

    LB7: Tow Haul Issue

    Well looks like you're not the only one. I'm having the same exact issue on my lbz. Tow haul light is on but my shift pattern from 4th to 6th is near like normal mode, downshift doesn't work right half the time. Haven't looked into the issue yet but hopefully someone can chime in and see what...

    Subwoofer Capacitor

    Just run a bigger wire and be done with. My white truck has 0 awg wiring. Barely has any dimming with the volume cranked up on a 1000w rms sub/amp. Bigger alternator helps too, although I'm running the stock alternator.

    Radio Wiring Gremlins

    Everything goes through the can bus data. Without the interface to communicate to the BCM, the speakers won't work.

    Do you have metro or PAC interface module? Those are most likely your issue.
