  • Q: What is the difference between your Base High Flow & Super High Flow Intake Kits?

    We often get asked the question of what the differences are in our high flow intake manifold kits for the LBZ & LMM Duramax diesel pickups. We have a couple different options available that suit pretty much any application available, and there are a couple of questions that need to be answered before selecting the perfect kit. Some of the questions that we ask customers before we recommend a kit for their application are:
    • What year is your pickup? (LBZ & LMM will require a different installation kit)
    • What region are you from? (Helps determine if a grid heater provision is needed or not)
    • What is your overall goal with the pickup? (Long & Short term)
    From there we can pick out the perfect kit for your application and get you all the parts required to do the job. The different kits that we have available will work on the 2006-2007 LBZ Duramax Diesel and 2007.5-2010 LMM Duramax Diesel. Although the kits may look the same, the installation hardware is different so it is important to know the correct year and engine code to ensure proper fitment. Once the year and engine code is determined, we have a couple different versions available depending on the customer’s truck setup. The different versions are listed below:
    • Base High Flow
    • Super High Flow
    • Low-Pro Base High Flow
    • Low-Pro Super High Flow
      Note: Every kit can be ordered with or without the grid heater provision
      High Flow Intake Kit Explanations:
      Our "Base" series is our economy, or entry level intake system. It will have a high flow intake tube that routes of the top of the alternator and as far forward in the engine bay as possible. We designed this kit for those running addition under-hood accessories or twin turbo/compound turbocharger setups. Our "Super High Flow" intake system is our elite system and will produce the most horsepower and torque. This system will come with our high flow y-bridge that sits in the valley of the motor and connects the two intake runners together. Our "Low-Pro" is just like the series stated above except for the fact that is routes "low" and behind the factory alternator so that will appear almost like the factory intake. The Low-Pro kits are great for those that want the "factory" look but with the performance gains of our DHD high intake kits.
    Here are a couple of images that will show the difference between the kits

    Q: What is a Warranty?

    In today’s world of lengthy auto warranties, both manufacturer and aftermarket “purchased” warranties, misunderstanding can occur. Our customers, and their customers (the end user) encounter problems at some point after their car has been repaired. We would like to set the record straight on just what a “warranty” is, and how the warranty process works.
      Many people today equate a warranty with automatic and total replacement of any part that goes bad for any reason. While that may be true of an item for which an additional extended unconditional warranty was purchased, the vast majority of parts, be they auto parts or any other commodity, usually have a time limit or usage limited guarantee. This guarantee is very specific in nature to replacement of any part found to be defective in its fit or function for the time limit specified. Manufacturers do an extremely good job of making a product suitable for use in variety of situations, and durable enough to hold up to the uses for which it was intended, however, after it has left their hands and has been sold into the world at large, it’s impossible to foresee all the circumstances that may be encountered that would cause failure. Many parts that are perfectly suitable for normal use are subjected to extreme stresses and situations that test the limits of its function. Many, if not all, of these stresses come from some form of excessive driver input.
        It is impossible to control how a part is installed and used after its manufacture, warranties are put in place to assure customers that they are buying a part off the shelf that meets all the specifications for which it is intended. However, since there is no control of its usage, these warranties are SPECIFICALLY LIMITED to defects in materials used and workmanship used to assemble the part in the factory. This does NOT mean an automatic replacement of any part that has failed. Anyone considering asking for a warranty on a part should first ask the question, “Why did the part fail?” Some reasons are pretty obvious. Others are not. Since most factories put their products through several quality control checks before being put up for sale, the first things one should consider are: How was the item used? What kind of environment was it subjected to? If it worked when it was installed, why did it quit after “X” amount of days?
          Most new items that are installed and work right from the beginning will continue to work properly for many weeks or years if installed correctly. Typically, a 90 day warranty is sufficient to address manufacturing quality concerns. If a part holds up for that long, it is likely to continue to do so. Whatever the time limit, it’s considered to be long enough to address quality and manufacturing concerns. Other reasons for failure may not be so obvious. In those cases, the seller of the merchandise, because of his or her experience in dealing with different types of failures of various items can make an educated speculation about whether a failure classifies as a defect. However, in ANY and ALL cases, the final determination of whether an item is actually a defect in manufacturing or materials or simply subject to driver abuse, environmental stress, or other causes, rests solely with the manufacturer. All parts sold by All Season Service/Dirty Hooker Diesel carry a 90 day warranty against DEFECTS IN MATERIAL AND WORKMANSHIP. The exceptions being electrical merchandise and any item for which the manufacturer has specified a longer time or mileage. Proof of material defects will be determined first by All Season Service/Dirty Hooker Diesel, and in specific cases by sending the item to the manufacturer for further examination.
            WARRANTY DOES NOT MEAN UNCONDITIONAL REPLACEMENT!

    Q: What is a DSP5 Switch?

    A DSP5 switch is a 5 position switch that can be installed on your Duramax Diesel that will allow you to switch between 5 different tunes on the fly. The Duramax Diesel ECM can store up to 5 different calibrations, which will allow the user to rotate between different tunes for different driving scenarios. We offer a hardwired switch for the LB7, LLY, LBZ, and LMM Duramax Diesel.

    Q: Can I use an Edge Insight Monitor for a DSP5 Switch?

    Yes, you can, but the current software is only equipped to handle the 2001-2004 LB7 and the 2004.5-2005 LLY Duramax Diesels. You can run either the Edge 83730 CS Insight or the Edge 83830 CTS Insight as your DSP5 switch.

    Q: If I install your PCV Reroute kit, will it throw a DTC code?

    Under no circumstances will a PCV Reroute kit throw a DTC code. There is no modification to the wiring harness or anything that would cause a code to be present after the installation process is complete.

    Q: Will your high flow intake manifold kits cause a DTC Code?

    These are a off-road use only product and will almost always throw a code for the EGR system. There are a couple of options that we recommend in order to remove the DTC codes present after removable of the EGR.
    • Install a handheld tuner that is EGR Delete compliant (PPE Std, H&S)
    • Have us re-flash the ECM for DTC removable ($75 fee)
    • Have us re-flash the ECM with a single or DSP5 EFI-Live tuning setup (prices vary)
    • Install a finger stick (which isn’t a 100% solution)
