When it comes to turbochargers for diesel trucks, Stealth Turbos have made a name for themselves by offering performance, reliability, and quality upgrades across the board. Whether you’re driving a 6.6L Duramax, 6.7L Powerstroke or a 6.7L Cummins, Stealth turbos can provide solutions for a multitude of different needs and wants—from stock replacements to high-performance setups. In this blog post, we’ll break down the key differences between Stealth’s STR, Mach 1, and Mach 2 line's of turbochargers and help you decide which one is the best fit for your driving needs.
It's no secret that Calibrated Power's newly designed Cummins 6.7L Stealth 64 Turbo HE351VE / HE300VG Turbos are making their rounds on a ton of 2007.5-2018 trucks. With Calibrated Power's success in developing, designing, and manufacturing the Stealth Turbo for earlier Cummins models, they now take prior knowledge and expertise to give these 6.7L Cummins a top-of-the-line replacement. Once you learn about what went into the design of this turbocharger. We are going to break down exactly why this turbo is the right replacement for your stock 6.7L Cummins.
ENOUGH AIR TO SUPPORT 700+ RWHP!
These are the first 4 upgrades you should make to your 2003-2007, 5.9L Cummins.
If you're just getting into the diesel game with a third-generation Cummins 5.9L you're on the right track. While people say the 12v motors are great for being able to handle lots of power and having lots of upgrades. The 24v is also a very solid choice for both of those same reasons. With more hp from stock than the 12v motors and some beefy internals, like forged rods that can handle over 800hp. There is lots of potential to be had.
It's a great truck from the factory, but if you're anything like the rest of us you're not interested in keeping it stock. Especially with the number of bolt-on upgrades available for the 5.9L. Why not make a great truck even better? Today we will show you the first 4 mods you should do to your 5.9L Cummins turbo diesel.
Your 6.7L Cummins NEEDS an upgrade!
The Ram 2500 and 3500 HD pickups with a Cummins 6.7L are made for towing. You know that. We know that. Everyone knows that. However, a lot of guys are clueless when it comes to which upgrades are worth it and which ones are a total waste of money.
WILL THESE BE THE RIGHT UPGRADES FOR YOU?
This list is based on an assumed set of circumstances. You have a 2013, 2014, 2015, 2016, 2017, or 2018 model year Ram 2500 or 3500 equipped with the Cummins 6.7L diesel engine. Your truck is completely stock (no modifications) or very near stock. You have not already deleted the emissions equipment or upgraded major performance components such as the turbocharger or high-pressure fuel system.
Drivers that use their truck as a truck will find this list especially helpful. Towing, commuting, and getting it up and moving when you need it to have to be balanced with reliability and efficiency. On the other hand, if you're looking to build a competition truck for sled pulling, drag racing or dyno competitions, our recommendations may drastically change.
- 2013-2018, Cummins 6.7L

- NOT interested in building a race or competition truck
- Cares about efficiency and reliability
- Want superior drive-ability
We have lowered our MAP pricing on the Stealth 64 Turbo:
Calibrated Power, home of DuramaxTuner.com, has ramped up in-house production of the Stealth Turbo line. This added capacity and volume of turbo production has provided an opportunity to lower MAP pricing on all Duramax models and allowed the Cummins 5.9L Stealth 64 to be a low price and top quality leader in it's category.

2003-2007 5.9L DROP-IN CUMMINS TURBO:
After the extensive testing we did in the Cummins Turbo Shootout back in 2013 we learned a few things about Cummins single turbo systems. This test featured 5 turbo's, recomended by the manufacturer, analyzed and compared side-by-side.
If you read the article featured in Diesel Power Magazine or listened to the episodes we did at the Diesel Performance Podcast then you already know there was no clear 1 winner. The reality of aftermarket turbo's is you have to sacrafice something to gain something. So we set out to develop a turbo that could meet our requirements for being a great daily driver, good for managing EGT's while towing and something we could cause havok on the streets with.

1000HP Daily driven Single turbo 5.9 Cummins
Generally the terms "budget" and "1000RWHP" are opposing descriptions. This build ties the two together while utilizing the highest quality parts in the industry. The owner, Mitch, who has owned this truck for some time has always envisioned a 4 digit street truck.
If you have been around the Cummins performance community for any length of time you understand how amazing it is to make over 1,000HP on a single turbo setup that is still streetable. Of course many people have made the power, but with a single turbo the big problem is spool-up and smoke output. With Mitch's truck we dialed in a parts package and our custom tuning so he could have the best of everything with his truck.
Manufacturing the best turbo possible takes top quality parts, a scrutinty to detail and multiple QC checks.
DuramaxTuner.com is excited to be manufacturing turbochargers in-house. It has given us a chance to dial in what it takes to produce the highest quality aftermarket turbo for the Duramax and Cummins trucks.
For those of you thinking about upgrading your turbo in the future, or if you are just a diesel performance nut, we thought you would like a behind the scene look of what goes into our Stealth turbo manufacturing.

Smarty MM3 Tuning Update!
We have been testing the new Smarty MM3 Tuning for the 1998.5 - 2016 Cummins. The software/hardware is the newest solution for custom tuning. Until now, the limited amount of accessible tables in the 1998.5-2002 tuning platforms made fine tuning challenging for highly modified Cummins trucks leaving them smokey, noisey, and generally not as smooth as other similarly modified trucks tuned with more advanced software. Now that we have access to said tables, we will be able to create clean, efficient power with these trucks.
One of the most exciting features to the new Smarty MM3 is Live Tuning. The live tuning ability allows our tuners to make real-time changes to the calibration on the dyno or during a road test where in the past we had to wait 7-12 minutes to implement one change. As you might imagine, live tuning will significantly shorten the developement cycle and allow us to quickly fine-tune a wide variety of modifications on-site at CPS. The second advantage to the live tuning software is the ability of the customer to change tunes (power levels etc.) on the fly on any of the supported platforms. These power levels will be supplied along with the base tune to customer at the time of sale (idealy).
Our discussion with the developers of this software/hardware package lead us to believe that improved scan tool functionality is next on the priority list. We would expect to see a very high sample rate scan tool along with several dozen of the most important PIDs in the near future for beta testing. This tool is critical to the development process. Without a strong scan tool we cannot validate our work, the better the tool - the better the final product and the better we can help our customers troubleshoot accurately if they need to.
