    Hey yall, I had some turbo actuator codes pop up on 2015 ram 2500. The codes were P003A, P00AF, and U010C. When my CEL came on, I stopped and shut the truck off to run the DTC. After running I turned my truck back on and drove it the last few miles to my destination. During the drive I noticed...

    2011 ram 2500 deleted and tuned I installed a reman turbo with pre calibrated actuator 2 days ago. The truck drives better but the exhaust brake doesn't work I feel like the actuator isn't moving at all due to the truck seems limited at the top end. My original turbo actuator burnt up on the...

    Just put a set of DFI SAC 7x0.013 injectors in the truck, would anybody be able to tell me the "hp" rating on these? i've looked at other threads on here and haven't really found a solid answer.
  4. 07.5 - 09 3rd Gen 6.7L Powertrain
    I have a 2007.5 3500 megacab G56 4x4 with 216,000 miles. I was told it has a tune on it when I bought it last march but I don’t know who from, it also barely roll any coal even when I lay into it which I thought was odd for a tuned cummins. Anyways the exhaust brake stopped working entirely...

  6. 2010-2012 Powertrain
    I ordered a new turbo with actuator already installed from USDieselparts, due to the previous turbo actuator being stuck open when the truck would turn on and only turning off when I disconnected the actuator. My only question is will I have to get the turbo actuator reprogrammed or how does it...

    I'm looking to replace the stock turbo with a Holset HX35. I found this one as a direct factory replacement: https://turboturbos.com/products/4035497?_pos=13&_sid=f2f5ec713&_ss=r The website says that it is for industrial engines and not for truck engines. Is there something different about...
  10. 2010-2012 Powertrain
    2011 Ram, only 58,000 miles. Based upon trouble code 226C, and consultation with Geno's Garage, I am confident that the vanes are sticking. The tech at Geno's said that while the actuator may move easily when cold it may bind when hot and thus "replace the turbo." $2200 plus $1000 core charge...

    One of our 06 5.9s hit a deer the other week and it looks like its going to be written off. Planning on buying it back as the truck is important to our family. I have a 1991.0 12 valve and I always LOVED the he351 on the late CR 5.9 and would love to have it on my 12 valve. I am assuming I would...

    Ive had my truck a little over two years now and I've always wanted to make it around 400hp to the wheels. I hardly ever tow anything and if I do its a ~5000lb boat/trailer. I do about a 50/50 ratio of city and freeway driving. I want to make more power because I use my truck to drive down to...

    My turbo is a borgwarner that I’m putting on. 69/73. It’s a t3 exhaust flange. Should I spend the money on a t4 housing or will a t3 be good. I have yet to purchase a manifold I was gonna buy a t3 manifold. My hp goals are 600-700 area in the future. 1999 24v Cummins.

    Just wanted to put in alpha OBD calibration success story for people to find if they're trying to figure out the best way to calibrate their stock turbo. I recently pulled and rebuilt my he351ve on my 2009 3500. I tried the cheapskate method that I've read about on here where you cycle the key...

    So I just bought a new 63/68/14 Smeding Drop in turbo from MDC Diesel for my 2005 5.9 and when I opened the box I noticed that it doesn't come with any mounting studs to mount to the exhaust manifold. I also noticed that on the new turbo that all four mounting holes dont have any threads for...
