    GT3788VA on a 2008 3500

    I saw this listed for sale online. What are the specs on it compared to a stock LMM turbo? How is the exhaust brake compared to a stock turbo? Thanks

    LMM: Service 4wd and Co 396 code?

    I lost 4wd and I get the code Co 396. Switch lights up when I start the truck. Nothing when I shift to 4 hi or low. Any ideas? I replaced the switch and that didn't help.

    6.4 PSD questions?

    My cousin and her husband just bought a 08 F250 with the 6.4. Truck immediately started having problems. Plugged DPF and EGR problems. How bad of a job is deleting the EGR? Can you use a blocker plate or do you need to remove the EGR system completely? Do you need to lift the cab to do...

    Allison 6sp: Strange acting in T/H

    The transmission in my LMM has been acting wierd. In tow haul when grade braking to a stop the torque converter does not maintain lockup. Occasionally it does but most of the time not. Sometimes it will unlock then lock back up very harshly as you might expect. It acts normal accelerating or...

    LLY injectors

    I'm getting ready to replace the injectors on my LLY. The stock injectors made it over 10 years and 243,000 miles. How long does it take typically? I figure I'll take your number and multiply it by 2 or 3 since I've never done them before. I'm probably going to buy an injector removal tool...

    Lly alternator

    Well after 10 years and 228,xxx miles, I think my alternator's days are numbered. My question is: I have the single alternator. Which one do I need? The 105 amp or 145 amp. I have the window sticker and there was no mention of alternator's on it. For some reason I thought it had a 145 on it...

    Zone lift opinions

    What's everyone's opinion on Zone suspension lifts? Strength, quality, relative ease of install? They seem to be priced right. I've never heard anything bad about them. They are made locally here in Michigan so that is a selling point to me. I would be considering the 6" system for my...

    LMM: Intake air temperature sensor

    Where is this sensor located? Is it in the Y bridge? Can you get to the electrical connector just by removing the turbo mouthpiece? Reason I ask is I screwed up and pulled the wire out of the electrical connector when I removed the mouthpiece today. I couldn't tell where the sensor is located.

    Site is not working properly on my I phone?

    Last night I updated my IPhone 5c with a software update. The site hasn't been working properly since. I can't push the arrow button at the bottom of the page and switch from say garage sale section to wheels and tires. It just kind of goes wherever it feels like. Sorry for the poor...

    Headliner starting to come loose over doors?

    Ok guys, on my 05 ECLB the cloth on the headliner is starting to pull loose and curl up over both the driver and passenger doors. To me it looks like the material has shrunk. The truck sat for about 3 months this winter in the snow so it is possible some water leaked in. (I ruptured my...

    Anybody own or work at a Napa or parts store?

    I've been having bad gelling issues anytime it gets below zero. I made my own dual fuel filter setup. I have a Napa 3418 water separator ( I don't know the micron rating of the filter) then it feeds into a Cat 1R-0750 fuel filter. Does Napa/Wix make a filter that would fit the same head as...

    More LMM VVT issues

    I've been having some problems with the truck lately. A couple weeks ago it popped an 0047 and I was able to fix it by taking the connector off the ECM and messing with the two wires that Dustin (chevyburnout1) told me to check last year when I got the code the first time. Started working...

    LMM Balance rates

    What should the balance rates be on an LMM? I've been having change fuel filter messages and occasionally low rail pressure 0087 codes when I run it hard. I have a new shimmed FPRV and a lift pumps btw. I just logged mine and this is what I came up with. Cyl1: -.28 cyl2:-.94 cyl3:-.98...

    4" tough country "strong kit" and Boss plow???

    I'm thinking about putting a 4" tc lift on my LLY and I'm wondering if I will still be able to use my boss plow? I'm sure the frame mount would have to be modified. Anybody have a plow on a lifted truck?

    II Silverbullet first impressions

    First of all the turbo is a 66/74/14 T3. Billet compressor wheel. Truck is an LLY with stock fuel, lift pump, built trans, and EFI live. Wow. This truck is fun. Very little lag and when it lights it hits pretty hard not the more gradual increase of the stock VVT. Normal cruising I'm...

    Tuning for dummies

    I've had EFI live since 07 and have never bothered to learn to tune. I want to modify my tunes from Duramax tuner to be able to run an S366 in my LLY. What needs to be changed in what tables??? I just want to be able to drive the truck after the turbo swap. I'll pay Nick for new tunes...

    LMM VVT turbo issues

    I've got a problem with my 08 LMM. It's throwing a P0047 vein position solenoid code. Veins in the turbo aren't working. I've replaced the solenoid and no change. Could a bad vein position sensor cause this code too? Stuck veins possibly? Any help would be great! Thanks

    Must have tools for turbo swap?

    I'm getting closer to installing my new S366( II Silver Bullet 66/74/14) on my LLY, and am wondering if there are any must have tools that I should have before I get started? Obviously a first time turbo r&r. Ben's install write up looks great and I will make some of Paint's penetrating oil...
