If your LB7 is still on its stock turbo, ore even an aftermarket turbo from decades past, its likely showing signs that it's on its way out. It's finally time to upgrade! You've been eyeing an upgrade for sometime, but which is right for you? You've seen all the videos and read all the literature. You may still have a few questions, well let's discuss which size turbo benefits you best, along with what custom tuning can do when paired with this upgrade.

Bigger is always our natural instinct, so a larger turbo wheel is way to go? It's more complicated than that. There are a few things to consider before buying your replacement charger. Let's get into what you need to take into consideration when looking at upgrading your LB7's turbo. 

 

Get SMART!

What are SMART Files? System Monitoring and Active Responsible Tuning.  That’s right, our calibrations not only add power they also monitor your engines’ activity and adjust appropriately to KEEP YOU SAFE. 

This cutting edge technology has been applied to all of DuramaxTuner.com and Calibrated Power Solutions tuning calibrations.  Developed from factory style algorithms and utilizing OEM sensors, this standard gives tuning customers the power they want and peace of mind they need to upgrade their vehicle.

SMART files available for:

• 2001 - 2020 6.6L Duramax
• 2016 - 2019 2.8L Duramax
• 1998.5 - 2007 5.9L Cummins
• 2007.5 - 2018 6.7L Cummins
• 2013 - 2019 6.7L Power Stroke
• 2018 - 2019 3.0L Power Stroke
• 2011 - 2020 3.5L EcoBoost
• 2015 - 2020 2.7L EcoBoost

The common myth that deleting the DPF and/or EGR to make power has gone on too long!

If you've been looking for ways to push your stock 2011 - 2016 LML with more horsepower, you have probably heard a lot of good information, but also a lot of misinformation. Most of the false things you'll hear are "the DPF will fail adding more power," or "More HP is going to clog the filter," and our favorite, "Deleted trucks get better MPGs!"  While you'll see these comments all over forums or on social media, there is simply no actual science or facts to back these claims.  So how much can your LML make? With tuning and a lift pump, you can expect over a truck with over 500 RWHP.



IT'S UNDERSTANDABLE WHY THE DPF SYSTEM IS HATED!

 

 

2.8L Duramax Tuning/Spade Instructions

 

We have streamlined the 2.8L Tuning Process! Tunes are now sent pre-loaded. HOWEVER, TO INSURE YOUR VEHICLE CAN BE PUT BACK TO STOCK YOU MUST READ YOUR STOCK FILES BEFORE FLASH. 

The Duramax engine has a history that runs deep.  It has the following still to this day and continues to up expectations in terms of power and everything else. While it's history stretches back to 1982, we are going discuss the more modern years. The 6.6L was introduced in 2001 and replaced the 6.5L and the company hasn't looked back since.

2001 - 2004.5 LB7

The 5.9L Cummins engine has been regarded as revolutionary and has a ton of fans that backed it in its heyday. It's history is even more impressive, we're going to talk about the engine's run from 1989-2007. 

1989 - 1993 

The Cummins engine had been successful in agriculture implements for a few years prior, so in 1989 Cummins and Chrysler introduced the 12 valve as an alternative the the V8 gas powered Dodge.  It was a hit immediately for those that wanted double the torque and a better option for fuel economy.  These diesel powered trucks were introduced stock with a 160 horsepower rating.  The truck was very simple.  Between 1989-1991 they offered a non-intercooled, turbocharged, and a three-speed automatic transmission, as well as a five-speed manual transmission option. Interestingly it had a rotary style mechanical injection pump.  These were the reason the truck was fuel efficient, but also why the truck lacked power. Another interesting point is how the original injectors were bigger than the next variation which arrived in '91.5.  The updated 12 valve now came with smaller injectors, a larger turbocharger, Cummins would introduce an intercooler to the truck, and the automatic transmission now came equipped with overdrive.  

There are a few circumstances when you will need to relearn your Vehicle Anti-Theft System (VATS) relearn.  This process is also known as resetting your Passlock or Passkey VATS system.  While the Passlock and Passkey systems are slightly different than VATS the trouble shooting them is fairly similar.  We suggest doing your research or have your truck professionally diagnosed prior to you begin this process.
