    05 LLY Sleeper Build

    For the money and your goals I still think the Allison is the most reliable. What your doing is the same thing that I’m doing with my 06 regular cab. You spend anywhere from 8500 to 25k plus on the tranny along. I have quite a few passes on my ccsb at 7200 lbs that are mid 6 area. I have not had...

    Valley turbo upgrade - compounds - built engine

    You are not going to have a problem with this setup unless it is a tune related created issue. It does take drive pressure to spool a turbo. Getting it in a acceptable place is where the tuning comes in. Don’t worry much about the turbo selection. Sent from my iPhone using Tapatalk

    Junk yard ECM, NOW WILL NOT START!

    Also if you flash you file in with the lowered time and key cycles you can do the relearn faster than leaving those parameters stock. Sent from my iPhone using Tapatalk

    LBZ cracked piston - What long block to with ?

    From my experiences deli PPE’s and Mahle Motorsports pistons have done ok as long as I stayed away from compounds. Once I did that they wouldn’t hold up very long at all. Fingers bowl design has done very good as well as forged. The Mahle Motorsport pistons from what I have been told from a very...

    In need of a good LMM DSP5 tune

    Your DSP file has to have been saved for autocal use by the person with the V2 that your autocal is linked to. If it isn’t then you can’t use the file. If it is then try flashing the file with using the autocal as a flash they device instead if loading it o. The autocal. There is no reverting to...

    LLY - Cracked piston

    I recommend those for any aftermarket turbo and fuel. When you get a stuck injector and you will get one from trying to lift the injector you will wish you had done those. Sent from my iPhone using Tapatalk

    Turbo options for L5P

    Intake runners are different. GM did a good job on design in respect to working on these as well as potential. It’s my favorite truck for a daily driver. Drivability, function and capabilities it is the top Dmax. I have people trying to get me to transplant into my Lbz regular cab but want to...

    Turbo options for L5P

    They are badass trucks but not that bad! They still are not a substitute for the aftermarket parts. Sent from my iPhone using Tapatalk

    Turbo options for L5P

    These are the two best stock bottom end L5P trucks that I’ve seen the sheets on. One is a single and one is a compound truck.

    lb7 dsp5 help

    Bully dog are notorious for corrupting files. Full flash with a good known stock file. Also full flash should take more than 40 seconds. Sent from my iPhone using Tapatalk

    Twins with Twins, Anyone?

    I was talking with Ryan yesterday. I always upgrade my returns as well to cut down on heat. What are you running for return line size? Where did you get the mango to AN fittings? Sent from my iPhone using Tapatalk

    Turbo options for L5P

    Guys have dynoed a little over a 1000 on stock internals. That doesn’t mean they will last forever but the L5P is a different breed compared to earlier generations. Sent from my iPhone using Tapatalk

    lb7 dsp5 help

    Have you verified through logging that it’s not switching. Your tunes are not a ton different so it won’t jump out at you unless you are going DSP to number 3-4 tunes. Sent from my iPhone using Tapatalk

    Turbo options for L5P

    The issue that others have had is with a stock vane cage there have been oil leaking out into the turbines and burning oil. DT is the only one now with a better vane cage. I haven’t used one or tuned one of their turbos on a L5P but they should be able to work just fine. Granted most of their...

    Valley turbo upgrade - compounds - built engine

    The turbo setup is a 366 stage 3 Dans Diesel turbo with a 475/87 1.3 vband turbine. We will be switching to a 480/96 with a 1.0 vband turbine. I highly doubt we will lose anything. Should pickup some in all aspects of driving. It tows that weight almost like there’s not much there. Sent from...

    Valley turbo upgrade - compounds - built engine

    We will tow 20k with my gooseneck and tractor with ease. It really comes down to tuning in the end. If you were using non vgt I would say go smaller but with vgt and good tuning a 66 will work. I would not go larger with using the truck period. You get to a point if maximum efficiency and after...

    Valley turbo upgrade - compounds - built engine

    The stage 3 chargers work well in compounds. Airflow is what it’s all about. Tuning will fix any issue you have with the charger. Realize torque convertor selection is key to any major aftermarket change. Sent from my iPhone using Tapatalk

    Another Broken Crank

    Things that I recommend are if you are building a engine don’t use stock parts. They are only designed to do so much. I would not run a stock crack, rods, pistons , springs or pushrods. People keep pushing the limits and finding the limits and because your friend had good luck with stock parts...

    LLY - Cracked piston

    I have ran cast piston top end gaps anywhere from .018-.025 and haven’t had a issue. I like to see .018-.020 myself. Depending on the rings manufacturer top and second rings have been all over the place with end gap measurements. You can gap them if needed but are setup up as ready to run in...
