    How to: Install DIC in gmt400 overhead console

    The difference between the DIC without mode and the one with is a matter of more than one wire difference. I believe I ran 7 wires to mine. It's most likely reading nothing because it doesn't sense that the truck is running.

    How to: Install DIC in gmt400 overhead console

    Mine does that when I turn the key to on but the truck isn't running. It displays fine but reads what you're seeing after 30 seconds.

    Viper (DEI) vs Compustar DIY

    Hi all, I've installed a few DEI remote start/security systems in the past for friends and family. All of which are still working great, now it's time to install one in my own vehicle. Any input on Viper vs Compustar for a diy? I like DEI because I can change settings with or without the...

    Evo versus standard power steering

    The shim would make the relief valve open sooner and give you less pressure. Looking at the piston on the left with the blue spring, that's not a gm spring and is why the nut is bottomed out. Gm used shims or no shims depending on if you ordered a Yukon vs a 1 ton truck with a plow package, the...

    Evo versus standard power steering

    Anyone reading this now, the relief valve shown in the pictures does not dictate how the steering will feel, it is a relief valve. If you hold your steering wheel at full lock, this is the valve that prevents you from going beyond that point because it will relieve pressure. A lot of people end...

    Having an issue with power steering 93 k1500

    Could be a defective control valve or the relief spring inside the control valve is weak or broken.

    Bad Vibrations

    Hi all, been trying to chase down a driveline vibration for the past couple of years now. 98 GMC 4x4 1/2 ton with a rcx 6" lift. I get a vibration that starts at 70 mph and doesn't go away even if I go faster, I also get a vibration for 1-2 seconds when I let off the gas going 50mph and over...

    Post lift questions

    Have had the 6" RCX lift for 3 years now and I've been chasing this Vibration on decel at 65+. Any body else have similar issues after installing this lift? Im Guessing maybe a bad pinion angle but the blocks were tapered.

    Steering Box Differences (88-98)

    From what Ive read, 88-98 steering gear boxes are interchangeble but there is 3 different models used at least throughout the years. I need to know the internal differences between them like ratios and whatnot.

    Steering Box Differences (88-98)

    I Need to know why the 96 trucks used a different box then the 88-95. Evo came out in 97

    Steering Box Differences (88-98)

    So after having removed the EVO Fitting on the back of my 98 K1500 power steering pump, i found that my steering is way too easy to steer on the highway. After doing some research, I was told to swap my gear box with one out of a 98. I also found that the P# for the 96 trucks were only used for...

    96-98 Vortec Alternator Upgrade AD244

    I ended up taking both of my batteries out and installed a friends new Optima battery, the truck was charging at about 14.3V initially and after approx 7 min dropped to 13.8V although It was charging at 72A the entire time at idle(the load never varied). Using a hydrometer, I found out that one...

    96-98 Vortec Alternator Upgrade AD244

    Are you saying to disconnect one of them and see what the alternator does? If so, I have not done that, I will try, it wouldn't surprise me if one of them is dead, I should maybe install a battery isolator and new batteries.

    96-98 Vortec Alternator Upgrade AD244

    13.8 V with no load, at full load (all accessories on) It was charging at 12.5V/ 85A. My problem is, my batteries (2) are always dead, 11.8 V when the truck is off, everything worked great when I had installed it, trying to determine whether I need a new alternator or batteries.

    96-98 Vortec Alternator Upgrade AD244

    To anyone who has installed the AD244, could you measure the charging voltage of the alternator? The most I'm seeing is 13.8 out of her at idle and 3,000, output drops to 13.2 V sometimes, I'm trying to figure out if that's the proper "factory set" voltage or if I simply picked out a "dud"

    Upping the stall speed on my 96 4l60e 4x4

    It will be useless buying a high stall converter unless you buy a cam. Install a cam with a power band of 1500-5500 then install you 2000 stall, your current cam has low end torque to help you get a load moving when towing, installing a higher 2000 rpm stall with a cam that makes peak power at...

    Speedometer/tire size issue

    Well, installing bigger tires always changes the way your speedo will read. How do you know it is accurate now? are you using a gps app on your phone? Your computer is programmed to perform a 2-3 shift at 35 Mph at 70% throttle, 40 Mph at 76% throttle so on so forth (those were just random...
