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

If you’re driving a 2001 to 2026 GM Duramax , there is a hidden danger lurking at the front of your engine. It doesn’t matter if you have a classic LB7 or a brand-new L5P; your harmonic balancer  could be the reason your engine fails catastrophically. At Power Forge Diesel in Yuma, Arizona , we specialize in preventing "The Snap." Here is everything you need to know about the Duramax crankshaft pin shear issue and how we can fix it in a single day. The Problem: A Design Flaw

This is a fun one to talk about. An aftermarket intake is what a lot of first time diesel owners first jump to when they go to upgrade their truck and rightfully so. They aren't too complicated to install and can be done right in your driveway here in Yuma, AZ  for pretty quick and easy horsepower gains. Cheap vs. Quality: What to Look For Now there are things you should look for when going to buy an aftermarket air intake on your truck. If you're already looking for the chea

The modern emissions systems for diesel trucks have come a long way. It doesn't mean we at Power Forge Diesel in Yuma  like or support emissions equipment development at all, but here's what you need to know to keep your truck on the road. Emissions Deletion vs. Maintenance I’m going to preface this by saying, the best way to make an emissions-intacked truck reliable over any other upgrade is to get rid of the emissions equipment. You’ll need to look up your local laws to see

You’ve probably heard of guys putting additives into their diesel tanks (whether it's a Powerstroke, Cummins, or Duramax) . You know, “those guys”. From the outside, it seems like these guys are either wasting their money, or maybe use their trucks primarily for heavy hauling. You don't need an additive right? Or, maybe you don't know where to look for a good one? Either way, a lot of people don't understand diesel fuel additives, and why you should use one. For those that al

This customer did not opt for an onboard air compressor, so we routed the fill nozzles through his license plate screw holes for a clean look. If you tow a lot, air bags can make your truck ride level and more comfortable, not to mention safer.

If you own a Dodge Ram Cummins  here in Yuma, AZ , you know that eventually you'll develop an exhaust leak. But do you know why Cummins engines are notorious for exhaust leaks? The Problem: Why Stock Cummins Manifolds Crack Cummins  makes a great engine. It's a straight 6 design and known for its torque output. Unlike its V8 counterparts, the straight size design uses a 1 piece exhaust manifold for all 6 cylinders. That extra length of the 2 cylinders makes for a longer exhau
