    30" LED Bar Install + Pics

    Just wrapped up the install of the 30" LED light bar we got from M & R Automotive - http://www.mandronline.com/ - they are also vendors on www.GMT400.com the 88-98 GM truck forum. The stock lights on these trucks are not very good and my cheap ebay ones aren't any better. This upgrade makes a...

    Torque management question

    Op did not say a model year so I grabbed a file from a 5.3 tahoe of this generation that shows typical throttle restrictions and sent it to Naomi to use. Even in cases where the restrictions in this table are less than this they can be found elsewhere in the program. I stand behind her original...

    How to LS Swap a GMT400 (or any other vehicle)

    TUNING Software The first thing you have to do tuning wise is install an operating system that correctly matches your harness and intended use.

    How to LS Swap a GMT400 (or any other vehicle)

    How do I build the harness for my platform? Use the harness that came with your engine when you bought it. That will save you the most time and money. If you are unhappy with the quality of the harness you have you can buy another used one or a new standalone one meant for hot rodders. If you do...

    How to LS Swap a GMT400 (or any other vehicle)

    WIRING One of the best things about working with a LS1 style (99~04) computer is the ease of setup for a standalone system. You can swap operating systems on the computer to meet your needs quite easily. I am running a truck operating system on my computer and the wiring I will discuss will...

    How to LS Swap a GMT400 (or any other vehicle)

    Ebay catch cans were installed using proper evap vent hose. The cans come empty so the trick to make them effective is to disassemble and stuff them with three bath puffs. The puffs turn into a long skinny tube once the string in the center has been cut. Each can holds one and a half puffs...

    How to LS Swap a GMT400 (or any other vehicle)

    On the topic of cranks – the largest single mechanical difference and hurdle to overcome and for tuning and getting a swap engine and computer to run between a LS1 style engine and the newer LS2+ (~2006+) style engines is that the crank sensor uses a different number of teeth. Yes the LS2+...

    How to LS Swap a GMT400 (or any other vehicle)

    ASSEMBLY Unfortunately, reading this alone will not make you a good mechanic. Time and practice makes perfect. There are elements of the assembly that will not be covered and will assume you are competent enough to fully disassemble and reassemble a vehicle. Remove the existing engine (and if...

    Ricer + stuff 2013: 4 wheel burnouts are mandatory (bought a suv for relevance)

    Ok so I know I barely ever post anything anymore and there's a host of reasons but this is my attempt at redemption. Besides it is better when you have more than one thing to say at a time. Let's see, the way I remember it, we left off after I fixed the ricer enough to limp around with the...

    Hi Gary would love to help you out please give me a call or email me both are far better to reach me than here. I'm not a fan of using the 4l80 transmissions unless absolutely necessary, they are power eaters and have awkward gearing. Whatever you come up with for desired power and budget we...

    Engine Swaps / Superchargers / Turbo Systems

    Hey Rod the common starting point for performance done right is about 10 to 15 thousand dollars. This includes upgrades/replacement of the engine, transmission and supporting systems. This does not include rolling stock or brakes which are highly suggested. Depending on your goals and budget we...
