    Brake issue

    I can confirm this. Went through 3 sets of napa fleet brakes and none of them performed or lasted as they should in 2 different vehicles. The rotors warped every time when I'm towing, ACDelco brake parts (or raybestos which makes the brake parts for ACDelco) lasted much longer and performed...

    When to upgrade!!

    50k for a 4 year old truck with nearly 100k miles is still too much imo. By the time you finish your payments, you're still dumping money into it for repairs from wear and tear. It ends up being more money into it that what it would cost to keep fixing your 21 year old truck that's already paid...

    01-10 steering box redhead ,PSC ,OEM

    Bumping it up Checking to verify if the Cardone 978418GB is not coming in as 4 bolt units opposed to the 6 bolts which every one is trying get before I order it. Nobody wants to do the same job twice over poor quality parts.

    Compound turbo tuning

    Bigger injectors are the next thing to add on this. Ended up having to put it back together so I could use it to take the family camping. I know my injectors are due for a replacement but its not making low rail pressure.. yet. Now I need to find out how big of an injector can the exergy...

    Compound turbo tuning

    I believe so. It's a JZ Mfg 63mm, got them through Brad. I originally wanted Danville and thought they were gone for good until Brad mentioned that JZ is practically a Danville turbo. I'm very curious what's Mark's tuning would be like with this turbo.

    Compound turbo tuning

    That's what I figured. The only thing I did to the tcm was to raise the shift points to keep it in the torque range. In factory, it would be too low of an rpm and lug especially when I'm towing with the t/h on. I did this with my single turbo setup to keep it from smoking at low rpms. Now it...

    Compound turbo tuning

    It does downshift depending on how fast I'm going with light throttle then mash it. I have a 1078 converter, that shouldn't be my issue? I do feel like it's in the tuning that I'm not aware of. Maybe more fuel down low in the pulse width?

    Compound turbo tuning

    Got the vanes almost dialed in, still trying to get it to spool like near stock. I'm uncertain at the moment if lowering the vane position would assist with the turbo spool up, I've made 5% adjustments by going more and less and didn't get much of a difference to notice. Also still adjusting the...

    Wheel fitment question

    Those wheels clearly look like a 0 offset, it won't push the wheels far out that much. It's probably a 4.5" backspacing. It'll be fine on your lowered truck. Won't stick out like an eyesore or dummies with wheel spacers.

    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...
