Boost Testing your diesel is essential!  Common symptoms of a boost leak include Increased Smoke, Higher EGTs, Excessive Lag, and Loss of Power.  Every truck that comes in our shop here at Calibrated Power, gets a boost test.   It seems about 85% of them have a boost leak when they show up.  Most of the time customers report still seeing peak boost on their gauges despite a boost leak. 

If you work with diesel trucks long enough, you’ll see leaks just about everywhere in the charged air system at one time or another. Remember, the charged air system includes anywhere from the turbocharger to the intake manifold. Your Intercooler system, Exhaust Gas Recirculation components, and even the Turbocharger compressor cover can all develop boost leaks.

Does your diesel have High EGTs, Excessive SMOKE, Increased Turbo Lag, and Less Power than it used to? Let’s talk about boost leaks.

Your truck needs air! Not a little bit of air. Your diesel engine needs all the incoming air it can get. Increasing air in the combustion process will help manager your Exhaust Gas Temperatures, Limit your smoke output, and increase your power.

This is why boost leaks kill diesel engines. Boost leaks can result in a smokey, laggy, dog-of-a-truck, which runs hot and burns fuel. Basically, the exact opposite of what you want from your diesel.

Boost leaks commonly occur in boots and clamps throughout the charged air system. That’s anywhere from the turbocharger to the combustion cylinder. Your intercooler system, Exhaust Gas Recirculation components, and even the turbocharger compressor cover can all develop boost leaks over time.

One of the most misconstrued topics in the diesel world is how emissions equipment impacts your truck.  Many people believe that deleting your Cummins DPF will enhance your truck’s performance and help solve DPF/EGR failures.  Well, the data around these systems has been building up for quite some time.  With enhancements of the DPF and EGR engineering, these systems aren’t like they were when they first hit the market in 2007.5.  When Cummins moved from the 5.9L engine to the 6.7L the DPF was brand new and as with many first-generation parts, failed often. 

Now, if you think that simply deleting your DPF is going to gain you 100 HP and 5 MPG, you're going to be surprised by what we have found with real-world data.  Not to mention, the current state of EPA involvement within the diesel performance community should be on your radar if you are looking for deletes. While social media, keyboard warriors may shout like they all the answers, you will want to know.

THE TOP 5 REASONS NOT TO DELETE YOUR CUMMINS DPF!

It’s common diesel knowledge that one of the weak points of the 2001-2004 Duramax diesel trucks is that the injectors will go bad. It’s something all of us LB7 drivers have had to deal with, the dreaded injector job. We’ve all been there or we are all about to get there.  First thing we will discuss is some of the issues you may experience when your LB7 injectors go bad.

 

 

The 2.8L Duramax came onto American soil in 2016 in the form of the Chevy Colorado and GMC Canyon.  This little Duramax is anything but small. This truck, and we can attest, gets the job DONE.

 

This Duramax is made to help you tow light loads and help that daily drive feel way more comfortable. It’s one of the reasons the SPADE tuning for this 2.8L platform has been immense. The immaculate MPG rating and towing capacity are what got you in the seat of this truck. GM really nailed it on this model and it continues to sell in large quantities. The 7,000 lbs towing capacity is more than enough for that pop-up camper, small boat, or that weekend race car making it out to the track.

When I told my wife about the truck, she said "Okay, if my truck is so great, why tune it?"

Well, as always, these trucks leave the factory with a lot to be desired. Tuning makes a night and day difference in your driving experience.  Adding switchable tuning setup to the truck is the difference between being able to tow the trailer, and feeling comfortable and safe towing that load behind you. Tuning adds reliability, better drive-ability, and it feels like a tougher truck overall.

 

 

Do you need to delete your L5P DPF?

We've all heard from forums and numerous outlets that deleting your DPF system is the way to go these days. What we never see backing these claims is data and tests. There is plenty of personal stories around a failed sensor or even the occasional DPF failure. However, once data starts fueling the debate on whether to delete or keep your emissions intact you may change your mind of what to do. 

When it comes to adding power to your 2011- 2016 Duramax, tuning with the EZ Lynk hardware is going to net you the most gains with the lowest dollar amount spent. Not only does quality tuning, like that from DuramaxTuner, add a lot more power to your stock truck, tuning truly is multifaceted to also ensure your truck stays on the road longer and give your five different tune options for your type of driving. Let's touch on why adding tuning with EZ Lynk to your LML will change your ride completely.  



Yes, 520 RWHP Tune Only

High powered diesel trucks usually represent a means of getting your toys to the adventure.  Whether it’s towing an open trailer full of fourwheelers and SxS’s, a boat, or the toy hauler, the ideal experience involves the driver and passengers in climate controlled comfort pulling in high gear without feeling compelled to watch the gauges.  The Roxor represents a departure from this.  It’s open cab and 1940’s era suspension doesn’t just take you to the adventure. Driving it is the adventure. 

As technology and research continue to accelerate the quality of the EGR system, it's something that due to it's poor quality at early inception has faced continual backlash.


EGRs on the cummins have been around now for over 10 years. While the infancy stage of the EGR came with many hiccups and issues amongst all the Duramax, Cummins, and Power Stroke diesel trucks. It’s understandable to see why so many dislike these emissions systems, but this isn’t the mid-2000s anymore. These systems have progressed over the years and we wanted to see exactly just how well.

When it comes to modifying your diesel truck, we all know that tuning is the best bang-for-your-buck. Tuning is not magic, it is a science. It takes time to understand all the intricacies and tables that come with it. All tuning is about is recalibrating your factory ECM, with that we’re able to work with factory parameters and modify them to what your custom tuning needs.
