    The New 17" PYOs from WCfab

    Here you go you ravenous animals LOL The paint cleans up OK for a 23 year old truck, but don't look too close 😬

    The New 17" PYOs from WCfab

    I need to wash the truck and put a new windshield in it (both scheduled for Friday), but I got impatient and had the new tires put on today. Here's a little teaser until I can get some glamor shots this weekend. The new setup next to my Suburban (stock wheels & tires) for size comparison: An...

    Moates Roadrunner Boot Issues

    I'll try to remember to post here when I pull that ECU out. My brother and I have been using that same guts kit for a decade and change, and I've never had any issues (save what I noted above) in all that time. I am glad to hear Moates is back at it. I might have to order a 2nd RoadRunner guts...

    Moates Roadrunner Boot Issues

    I do still use a Moates RoadRunner. I move the guts between 3 different ECUs: LB7 ECU, 512k (15166852) LS1B ECU, 512k (12202821) LS1B ECU, 1M (don't have the number written down) I only use it with EFILive, and it works pretty well, but some OSes don't like it. Never had a no-boot, but it...

    trololol Sensors came in today, tire install is scheduled for Friday. But I might try and move that up now that I have the sensors.

    300k on transmission fluid

    I've been using Castrol Transmax DEX/MERC (which is a Dex 3 spec fluid). Use it in my main truck (790 HP / 1300 lb-ft at the tires) and my Suburban (425 HP / 750 lb-ft). That's what my builder said to use for the warranty and I saw no reason to stop once the warranty was up, though they said any...

    The New 17" PYOs from WCfab

    Why must I be a stickler for OEM parts? I retrofit TPMS into my 2003 and I know the 15114379 sensor works, but mine are now 10-11 years old so I want new ones. I have ordered 4 sets so far, with a 5th set on the way, and only 3 of the new sensors weren't 7+ years old. They appear to manufacture...

    I'm still waiting on replacement TPMS sensors and hubcaps, so I'll probably install them end of next week at the soonest. Sent from my CPH2655 using Tapatalk

    Aluminum Radiators?

    I agree, something seems off. I'm on my original radiator on my 2003 with 370,000 miles now, and I make 790 HP to the tire. Sent from my CPH2655 using Tapatalk

    At least one baby Duramax still exist

    That in a Suburban 2500 would've been awesome. I was disappointed when GM killed it. Glad one survived the purge. Same with at least one EV1, despite GM's best efforts. Sent from my CPH2655 using Tapatalk

    The New 17" PYOs from WCfab

    No, I've got the torsion keys set to the stock position. The GMC front end is more forgiving than the Chevy in terms of large tires from what I've seen, and keeping the torsion keys at stock means I don't grenade CVs when racing and the ride quality is still good. Sent from my CPH2655 using...

    The New 17" PYOs from WCfab

    OK, got the measurements I wanted, and hopefully the measurements y'all wanted too! I have been running stock Hummer H2 rims with BFGoodrich All-Terrain T/A KO2 tires in 315/70R17 (~35" x 12.5"). With the H2 rims, there is only minimal trimming of the lower plastic bumper and some "massaging"...

    The New 17" PYOs from WCfab

    My set shows up this weekend. As far as I can tell the size and offset is identical to the GM factory Hummer H2 rims which work great with the 315/70R17 tires (35x12.5") I like to run. Yeah, they're stupid expensive but I love the stock rim style, but want to stick with 35s, and it's been a...

    S&B 10-1023 LB7 calibration

    Sort of forgot to report back here, but been running the calibration with the 10L "reserve" for the last 5 years and it's been flawless. Range estimates are darn close, and the fuel gauge matches how much fuel I end up putting in when I do fill up. Not sure why S&B still claim the range isn't...

    Coolant loss into oil and no external leak! Help

    If the oil cooler is leaking, I would expect to see mixing both directions. When the engine is running, oil pressure is 15-60 PSI and coolant is 15 PSI, so you would get oil in the coolant. But when the truck is shut off, oil goes to 0 PSI but coolant stays at 15 PSI for a while, and will put...

    High EGTs w/ KB Diesel 64mm

    Which PID are you using to read boost? The LB7 will cap the reported boost on the SAE PID if I recall correctly. There is a PID that can read higher, but the stock boost sensor only reads up to like 30 PSIg so with an aftermarket turbo you really want to swap that to a 3-bar or higher then...

    Bought a Sierra as Donortruck - now he stay

    Just little things, like your comment on the sheetmetal for the repair part being so thick compared to normal. Though that might be a truck vs. car thing more than US vs. Germany thing. The rest of the differences make sense, as the parts are hard to get over there so it makes sense to...

    I really enjoy reading about the restoration and seeing the little differences over there vs over here. Looks like you are making good progress and doing a very thorough job. Thanks for keeping us updated! Sent from my CPH2655 using Tapatalk

    Bought a Sierra as Donortruck - now he stay

    Here's the pin out for the inside rearview mirror. See if those pins/colors match. I don't see a connector like you have for the roof marker lights, but I might be looking in the wrong section of the manual. Sent from my CPH2655 using Tapatalk

    Bought a Sierra as Donortruck - now he stay

    That wire on the headliner is probably for the rearview mirror. The higher trim levels have the temperature and a compass in the rearview mirror. If all the wires are present, you might be able to upgrade yours by getting the rearview mirror and adding the temperature sensor at the front of the...
