The Ford 6.0L Powerstroke diesel engine has one of the most polarizing reputations in the automotive world. From the factory, it arrived with a handful of critical engineering flaws that gave it a bad name. But ask any specialized diesel technician, and they’ll tell you the exact same thing: once you address those factory shortcomings, the 6.0L is an absolute beast that will easily run past 300,000 miles. At Power Forge Diesel, we don't just fix these trucks—we re-engineer th

If you drive a modern Ram Cummins diesel, you already know the engine is virtually indestructible. But if you’ve added power tuning, or if you regularly tow heavy loads through the grueling Arizona heat, you probably know the weak link in the chain: the 68RFE transmission. The factory 68RFE is notorious for premature failure when pushed hard. From valve body issues and torque converter slip to burned-up clutch packs, it doesn't take much to put your truck out of commission. W

When it comes to heavy-duty towing, reliability is everything. If you're driving a 2007.5 to 2024 Dodge Cummins, you already know these engines are absolute workhorses. However, even the toughest factory setups have a few hidden vulnerabilities—and if you are running a stock, emissions-on truck, keeping things clean and efficient is vital to the life of your engine. We recently had a 2016 Dodge Cummins 3500 come into the Power Forge Diesel garage for a full charge-side upgrad

When you live and drive in Yuma, Arizona, a mediocre air conditioning system just isn't going to cut it. When the summer heat regularly pushes past 110°F, you don’t just need your AC to work—you need it to blow ice cold. We recently had a classic Ford 7.3L Powerstroke roll into the Power Forge Diesel garage. The owner’s complaint? The AC system was blowing cold, but it just couldn’t keep up with the brutal Arizona sun. It was lukewarm at best when idling, and it took way too

When summer hits Yuma, Arizona, it doesn’t just get warm—it hits triple-digit, relentless desert heat. For everyday drivers, a weak air conditioning system is an inconvenience. For diesel truck owners who depend on their rigs for heavy hauling, hot work sites, or long-haul towing, a failing A/C system is an absolute dealbreaker. At Power Forge Diesel, we are already seeing a wave of diesel pickups coming into our shop with A/C systems that simply aren't ready for the brutal Y

The Fatal Flaw in the 6.7L Dodge Cummins If you own a 2007.5 to 2024 6.7L Dodge Cummins, there is a ticking time bomb under your hood that many owners aren’t aware of until it’s too late. It’s known in the diesel community as the "Killer Nut." At Power Forge Diesel, we’ve seen firsthand how the factory grid heater design can lead to catastrophic engine failure. Here is everything you need to know about this issue and how we can help you prevent a multi-thousand dollar repair

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

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.

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.

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
