Like any well educated Duramax owner you go to DuramaxTuner.com to check out everything you can on the Stealth turbo, but you're still wondering which is right for you.
Now you may have the urge to simply pick the turbo with the highest peak power. Maybe your thought process is to go immediately at the cheapest price.

However, there are a few things we would recommend you consider before making your buying decision. It can help you save money and time in the long run, so let's dive into which suits you best.
There are a few things to consider before picking a new turbo for your LB7:
You use your truck for daily commuting or hauling the family and trailer for a long weekend of camping, you’re rolling up to your work or that campsite and you notice the LML go into regeneration (regen). You can’t keep driving as you should because you got a job to do or things to unpack. You can’t help but wonder what can be done to keep your LML from going into this cycle as often as it does, we’ll get into that in bit, first let’s look a little more at DPF regen.
The DPF takes essentially 700 miles or 18 hours of drive time to put it to the maximum values of normal calculated mass soot levels, which if you were curious is 44 grams. Active Regen describes the procedure your truck goes through to burn that accumulated soot. To do this, fuel is dosed through a 9th injector directly into your exhaust. Many drivers have noticed a drop in MPG and even potentially a lack of power during regen.
A popular theory is that if you go through regen less frequently, your MPGs will go up. So, how can you go through less regens?

Single, Drop-In, 800 HP, LB7 Turbo:
When you're looking for the ultimate Duramax turbo, everything really depends on what caters to your wants and needs for your truck. This turbo was created with diesel enthusiasts such as ourselves in mind. We asked what everyone wanted in a larger turbo and the Stealth 67 G2 is what we came back with. This new addition to the Stealth line is superb and fits in the family of our in-house designed, industry leading turbos. Let's delve into what this beast can accomplish.
The Stealth 67G2:
LML SPADE & Smart EGT Control:
Exhaust Gas Temperatures (EGTs) give you an insight as to how much stress you are putting your engine under. It is the most accurate way to monitor if your current activity is safe for the engine.
In a factory tuned truck high EGTs would most commonly be a sign of a physical problem like a boost leak. However, a tuner added to an aggressive driver could result in EGTs beyond the desired limit.
Most examples of this also include a mismatch of your tune level and truck operation. Such as the guy towing in his race tune.
The LML SPADE by DuramaxTuner.com now includes a Smart EGT Control feature.
What crashes an LB7 and LLY ECMs?:
If you have a 2001 - 2004 (LB7) or 2004.5 - 2005 (LLY) Duramax and have been thinking about tuning it, this article is for you.
As you're probably aware, ECMs have some small risk of crashing during a tuning flash. Browsing the forums online you definitely already picked up on the fact that the LB7 and LLY ECMs are more suscepitble to the issue.
To make sure you aren't stuck stranded somewhere far from home follow these tips:
6 Speed Conversion Kit for the LB7 & LLY 5 Speed Allison:
Your 2001-2005 Silverado/Sierra HD diesel is powered by either the LB7 (2001-2004) or LLY (2004.5-2005) Duramax. That Duramax is tied to one of the most popular automatic transmissions, the Allison 1000.
While the Allison 1000 was a big step forward, it still needed improvement. The LB7/LLY models came with 4 gears and Overdrive, or "5 speed". In 2006 General Motors (GM) released the 6 Speed transmission for the new at the time LBZ model and other HD trucks.
Without getting too technical about how automatic transmissions work, they did not actually add a physical gear. The Allison works through a series of clutch packs being applied with hydraulic pressure to create different gear ratios. What GM actually did was design a brand new valve body and improved tuning to achieve the 6 speed Allison 1000.
DuramaxTuner.com now has a 6 Speed Conversion Kit which includes a new valve body and custom tuned TCM that allows your truck to achieve 6th gear.
Who Will The 6 Speed Conversion Kit Help?
5 to 6 Speed Allison Conversion:
The Allison 1000 transmission equipped in the 2001-2005 HD Silverado and Sierra was considered to be revolutionary when it was released.
Owners rave about the smoothness and reliability of the 5 speed Allison transmissions. They're able to reliably handle the strain of towing heavy and still have reasonable street manners for commuting. Duramaxtuner has recently invested considerable time into the AL5 controller to build out the shift shedule and quality of all the 5-6 and 6-5 shifts. Matched with our upgraded valvebody this kit will have your 15 year old truck shifting like a 2018 model.
As most technology has advanced over the last 12+ years, so has transmission technology. You've probably noticed that just about everything on wheels has more gears these days. Starting in 2006 all Duramax powered GM trucks were given an extra overdrive gear (.61). Since then, they haven't looked back.
Why is that? Why does your truck need more gears?
