  1. What's new in this club
  2. Talked to Rich today around 2 and he said new turbo is in, they are working on the ball joints and getting the alignment done this afternoon. Tomorrow (Thursday) all they have left is the gauges. Right now it feels pretty positive I’m getting my truck sometime tomorrow.
  3. Just dropped my truck off at Dirty Diesel Hooker to get new turbo installed, ball joints and the maxtow gauges.
  4. Yesterday I received my dash cluster back from Circuit Medics from changing the soldered on bulbs to LED bulbs and wow does it make a huge difference and they were fast. When Fed-Ex dropped it off it was one business day for them to fix it and ship it out. Very happy with my decision to send it.
  5. I don't like fender flares at all but GM trucks (GMT800) all have them and they collect salt and rust out everything behind the plastic. So I took off my flares and then found my tires just cover my truck in mud, dirt, salt. its just no good but trying to find some decent fender flares that just don't look stupid is tough. Ordered some Bushwacker flares from Vehicle Accessories. Not sure I like them or not. I don’t have a lot of choices.
  6. So what's next for my beauty... Well I'm broke so just some minor updates like: Side Window Tint (if the truck is a rockin....) Window Visors (the slim kind.. I'm tired of getting rain and snow coming in my truck when I need to vent the air in the truck for some reason) The amp override switch (79105-01A Override switch with STA Controller) to open the amp steps and leave them out so when I get a car wash the running boards get clean and so do the rockers. In my opinion amp should just include this switch for all the money we spend. After using it the AMP Running B
  7. So Calibrated Power (aka Duramax Tuner) completed the work on Jan 7th, 2021 and I’ve fell back in love with my truck. Driving my truck now is how I expected it to perform originally. Sales Order_SO1724_1610039898626.pdf
  8. Scheduled Jan 4th, 2021 to have Calibrated Power (duramaxTuner.com) replace the injectors.
  9. I called Calibrated Power (duramaxtuner.com) found at: 455 Borden St, Woodstock, IL 60098 Talked to Chris which was a pleasure to talk to on the phone, not trying to sell me up on anything but trying to make sure I'm happy with the truck after they are done with it for what I use it for. Just spit balling over the phone, Chris said an ideal setup for what I need (which is solid highway driveway back and forth to detroit and the occasional trips pulling the heavy RV trailer) the following would be on the table: Sportsman Exergy Injectors Fuel Pressure Relief Valve
  10. injector issues.. seeing white smoke from exhaust. Time to get prices on getting it done. $4200 10 days (2yr warranty) factory bosch injectors - diesel pros and performance in swartz creek (Diagnose issue: $95/hr)
  11. Tire Size whats on it now are 35x12.50 R18LT 10ply LOAD E range (mainly for the hauling) Also I have Toyo R/T (which is Rugged Terrain which is a mix of the All Terrain tires and the Mud Tires but they are LOUD but not as loud as a mud tire but someone who drives highways alot, stay away from these unless you like to hear your tires always singing) Noise Test with the 35 Toyo R/T tires Toyo35r-t_noise.mp4 But I’ve been interested in some better mileage and the key is to go more narrow of a tire. Possibly move to a 33 but trucks with a 6" lift and 33" tires
  12. Removed the fender flares (dirt/salt traps) initial removal after I hosed off the Dirt and did my first pass with the eraser wheel it appears the stock fender flares rubbed right through the paint in spots. I brought it to Clarkston Auto Body and they said they can repaint it for around $1200
  13. Changing the glow plugs fixed the check engine light. one side of the truck they used seize and it was pretty easy to change, the other side they didn't use seize and had after market glow plugs and was a bitch to change.
  14. A common issue with the GM 6.6L Duramax engine is white smoke at idle. Worn and damaged injectors are often the cause however there are other causes and considerations that should be looked at prior to injector replacement. INJECTORS STUCK OPEN OR WITH EXCESSIVELY LEAKING NOZZLES DIANOSIS 1. Remove IGN 1 relay. 2. Remove the glow plug from the suspect cylinder(s). 3. Crank the engine and check for fuel spray coming out of the glow plug hole. Caution: Make sure you are not in front of the glow plug hole during this process. 4. Replace any injectors on the cylinders that spray fuel.
  15. Changed the glow plugs in my LBZ Duramax Diesel and learned a few things. First, why did I jump into this project? Whenever it was cold out (which is often here in Michigan) the glow plug would come on and when it went away the Check Engine light would stay on. So I pulled out my spade tuner and read the code which was ECM P0672. Review what the code is its defined basically everywhere as a semi generic code but with some specifics like what cylinder to troubleshoot So which one is the #2 Not that it really matters since when you are changing them its always recommended
  16. Now getting a Check Engine light when the glow plugs are trying to warm up the engine to start. Checking for codes it shows ECM P0672 which is a bad glow plug in cylinder #2 which is about $20 for the glow plug and looks like its a do it yourself type of job. Its like changing a skinny, tiny spark plug.
  17. Added EFI Live DSP5 and a TCM tune all from calibrated power (duramaxtune). Now just trying to get the truck to find its groove. It doesn't feel like it knows what to do. I have been keeping it in Position 1 which is the stock+ tune and I plan on keeping it here until it feels like its regained the normal shifting and driving and then I'll kick it to Position 4 which is the Eco mode to get those high miles per gallon (especially driving back and forth to Detroit for Kate's Chemo). Then Position 2 and 3 are for towing which will also come in handy. You can tow with Position 1 (stock+ tune)
  18. Saturday (2020.04.11) performed Trans Filter (internal and spin on external) replacement as well as 3 gallons of new fluid and the internal trans filter lock and a new deep sump pan. Miles: 104,000
  19. It arrived yesterday and discovered some surprises Fuel Filter is at 1% Only 1 key and 1 Viper keyfob Viper Keyfob doesn't lock/unlock or remote start vehicle Steering Wheel Controls don't light Fuel Gauge moves super slow (not sure if its accurate) No way to lock/unlock doors GM Delco Radio (6 disc) doesn't support MP3 CDs Steps are right up against truck. Fuel Filter No big deal, ordered some AC Delco Fuel Filters on Amazon for $30/each. Pretty easy to change Key issue When I find a dealership that is open, I'll get two n

  22. It might be sold.. a guy came on Saturday, looked, drove, looked gave a $1000 down payment for the purchase price of $52,900 but I am including a B&W fifth wheel hitch for the RAM puck system. He applied for loan Monday morning.
  23. Attention Students.. Attention! Don't make me... In 1998, General Motors and Isuzu teamed up to establish engine manufacturer DMAX Ltd to create a brand-new diesel engine that would be the first high-pressure common-rail, direct-injection powerplant to hit the U.S. vehicle market. 2000 – GM debuts the LB7 Duramax diesel engine with 300 hp and 520 lb-ft torque in ’01 ¾- and 1-ton trucks. The 6.6L V-8 turbodiesel engine featured aluminum heads with 32 valves on a cast-iron block, high-pressure, common-rail, direct fuel injection, a fixed-geometry turbo, injectors mounted under the
  24. I know Ford used Caterpillar Diesel Engines in some older Ford trucks and I was curious who owns Caterpiller and I was very surprised to find out that Caterpillar engines are copies of the Cummins motor and also a Cummins owned company. Now who owns Cummins? No one does, they own themselves. Ram was the first company to come to Cummins and ask for them to make a diesel fo their trucks which produced the first light duty truck in 1989. This is the same engine that was found in Case agricultural tractors. The 6BT or more known as the Cummins "12-valve" (since it has 2 valves per cylinde
