If you own an 01-05 Duramax with the 5-speed Allison transmission, this one is for you. The LB7 and LLY Duramax engines are held in high regard because of their reliability and lack of (or early) emissions equipment. These trucks are known to go hundreds of thousands of miles completely stock and maintain great reliability when upgraded and tuned. For many diesel enthusiasts—myself included—the early 01-05 Duramax was our first diesel truck. The 5-Speed Limitation on Arizona

If you own a 6.7L Dodge Cummins , you know that fuel delivery is the heartbeat of your engine. Recently, a customer brought their 2008 Dodge into Power Forge Diesel here in Yuma, Arizona, experiencing inconsistent fuel pressure issues. Our solution? A complete FASS Fuel System upgrade. Why Your Cummins Needs a FASS Fuel System The stock filtration on many diesel trucks often falls short of protecting sensitive high-pressure components. Here’s why we recommend FASS for every

Location: Power Forge Diesel – Yuma, AZ If you are looking for the best Banks Power and S&S Diesel 6.7 Powerstroke Upgrades , look no further than Power Forge Diesel in Yuma. This week we performed several Banks Power and S&S Diesel 6.7 powerstroke upgrades on a 2014 Ford F-350. If your truck is acting sluggish or throwing exhaust codes, this "domino effect" of failures might sound familiar. The Symptoms: Low Boost and Constant Regens The customer brought the truck to us repo

We got this customer set up with the banks boost tubes and intake horn air upgrades. We also worked on a full exhaust system and other reliability upgrades. Along with those other reliability upgrades, we set this truck up with custom engine and transmission tuning. Can't say too much about this job, but this customer can now have the peace of mind that his truck is more reliable and no longer has to worry about reduced power mode.

This 2014 Ford Powerstroke came in for a preventative upgrade to protect the fuel system from CP4 failure. We installed an S&S Diesel Disaster Prevention Kit to help prevent contamination from spreading through the system and causing costly damage. Vehicle: 2014 Ford Powerstroke 6.7L Service: S&S Diesel Disaster Prevention Kit Install Purpose: Protect fuel system from CP4 failure Parts Used: S&S Diesel Motorsport Kit Location: Yuma, Arizona Protect your Powerstroke before it

This 2007 Cummins came in with fuel system issues and poor performance. After diagnosis, we replaced all 6 injectors along with new high-pressure fuel lines and feed tubes to restore proper fuel delivery. All components were installed with precision and verified for leaks and performance. Vehicle: 2007 Dodge Cummins 5.9L Service: Injector Replacement (6 injectors), High-Pressure Lines, Feed Tubes Symptoms: Poor performance, fuel system issues Parts Used: Quality components so

The 6.7L Powerstroke is a workhorse, but it has a "ticking time bomb" known as the CP4 injection pump . At Power Forge Diesel , we recently had a 2013 Ford Powerstroke in the shop for a proactive overhaul to ensure this truck stays on the road—not on a flatbed. The Problem: The Infamous CP4 Failure If you own a modern diesel, you’ve likely heard the horror stories. The stock CP4 pump is notoriously sensitive to fuel lubrication and contamination. When they fail, they "grenade

We installed a Banks Power Monster Ram Intake Elbow install on this 2020 Dodge Cummins. This customer got the new dual heater intake to remove the notorious grid heater bolt/nut. This should be the first thing all Dodge Cummins owners do. If that bolt/nut melts off and drops into the intake, it can and will take our your engine. This customer has emissions intact and the banks intake accommodates for that. He is now enjoying peace of mind, as well as a slight power gain and b

Everyone that has a CP4 pump (2011-2024 Powerstroke 6.7L, 2011-2016 Duramax 6.6L, 2019-2020 Cummins) needs to know that the current failure rate (Feb 2026) in the U.S.A. for the CP4 is every 1 in 14 trucks. That's 7% of every truck with a CP4. That might not sound like much, but in the diesel world, that is a ton. That is approximately 140,000 trucks in the US alone that have had a CP4 pump failure. The Reality of Powerstroke CP4 Failures Ok, so I'll mainly be addressing the

The customer did not want tuning or anything that would hurt his transmission. So, we went with this DuramaxTuner Stealth STR Turbo. This turbo supports up to 625hp, lower EGT's for towing, heavy duty parts for longer reliability than stock, faster spool up for low end torque, zero turbo surge, and an unlimited mile 1 year warranty. Best part is, this turbo is a complete drop in with a new actuator. This can be installed without a tune and still get +50 hp and better fuel eco

Cummins Exhaust Solutions at Power Forge Diesel: BD Diesel & ARP Upgrades At Power Forge Diesel in Yuma, Arizona, we recently saw a textbook case of why the factory Dodge Cummins exhaust design fails. We just finished a full manifold overhaul on a 1995 Dodge Cummins to save the engine from a common, but dangerous, failure point. The Problem: Warped Manifolds & Collapsed Intakes The stock one-piece exhaust manifold on the Cummins 5.9L is prone to shrinking and warping after y

There are a few ways to fight gelled fuel during the winter time. Now, Power Forge Diesel is in Yuma, Arizona , which rarely gets below freezing. However, fuel gelling issues can start as early as 32 degrees. You should be running a fuel additive to fight this anyway. We recommend Optilube All-Season (not sponsored). Run this additive regardless of the temperature outside. We have a separate post about fuel additives, but what are automatic ways your truck can de-gel the fue

If you own a Chevy or GMC Duramax, there is a "ticking time bomb" under your hood that you need to know about. From the factory, the harmonic balancer is held in place by a small alignment pin that is notorious for shearing. When that pin fails, the balancer spins freely, which frequently leads to a broken crankshaft and a total engine loss. We recently had a customer in our Yuma, Arizona garage who chose to get ahead of the curve by installing a harmonic balancer keyway pin

Your transmission is basically a big hydraulic piece of equipment. It uses transmission fluid to perform every function of your transmission. It is no mystery, especially with the new GM Duramax and Ford Powerstroke 10 speed automatic transmissions, that the cooler your transmission fluid temperature, the longer your transmission will last. Many people don't know how to get lower trans fluid temps. But we at Power Forge Diesel in Yuma have the ultimate setup for the best tr

If you own an LB7 Duramax , you have probably replaced injectors. Even if you haven't owned an LB7 duramax, you have probably heard of the infamous injector issues that plague this truck. Before we go into the injector fix, you need to fix the injector cup issue in the heads themselves. PPE and Fleece both make heads that do not have injector cups in them, we have another post that goes into depth on those. So how do you fix the injector issues? The $13,000 Dealership Quote

It is obvious that your diesel engine (whether Powerstroke, Duramax, or Cummins) has coolant in it. I don't have to go into much detail on what your coolant system does. I will say that your radiator is designed to function under normal use, but what are some reasons you should look into a Mishimoto radiator for your diesel truck here in Yuma, AZ ? The Problem with Stock Radiators (Plastic End Tanks) The factory radiator (for the most part) is sufficient for normal everyday

We set this customer up with 5 level on-the-fly tuning. Levels: 1 Stock, 2 Tow, 3 Street/Economy, 4 Performance, 5 Race. Our tunes are reliable and designed specifically for each truck with its unique upgrades if any. We also installed an Amsoil Bypass Filtration System for this customer. This system filters out the tiny soot particles in the oil caused through normal diesel combustion that a normal filter cannot remove. Amsoil replaces the normal filter with a remote filter

Many people tow in Yuma. Whether you're a winter visitor escaping the cold or a local heading to the dunes with a heavy toy hauler, we put our trucks through incredible stress with these massive trailers. While modern trucks are rated for heavy loads, "rated for it" doesn't always mean "built to last through it"—especially in the Arizona heat. So, how can we increase the life of our trucks while hauling heavy rigs? At Power Forge Diesel , we recommend these three essential up
