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!
520 RWHP TUNE ONLY LML DURAMAX:
The 2011 - 2016 LML Duramax came rated at 395 horsepower and 765 ft/lbs of torque. That seemed like an amazing amount of power when this model was first released but these days it is dwarfed by the available power of brand new trucks.
Furthermore, that whopping 395 HP is a peak power rating, meaning that you probably won't produce that much power during normal operations. In fact, many owners complain that the power delivery of the stock tune is too soft. This is why custom tuning is so important for the LML Duramax.
Here are some of the things tuning your LML can help with:
- Increased Peak Horse Power
- Improved Shift Quality
- LML Dead Pedal Resolution
Ever wonder what you need to push your stock truck to its limit? We know the answer, and we created this article for you. For 600-640 RWHP you will need to keep in mind all the supporting modifications you need to maintain reliability.
Custom tuning is going to ask your truck to perform at a higher level. The same goes for upgrading your turbo, transmission, fuel system or any other performance orientate component. The best way to maintain a moderate level of reliability while upgrading is to address these issues once and do it right!
Here is the list of what you need to make a reliable 600+ RWHP LML with a DPF still on it:
- EZ Lynk AutoAgent 2.0 w/ Support Pack & LSP5 Switch
- LML Stealth 64 Turbo
- 10mm Cp4 Exergy Stroker Pump
- DT550 Built Transmission
- S&B Intake
- Tie Rod Sleeves
- Traction Bars
- Fass 165 Lift Pump
- Beans Fuel Tank Sump Kit
- Edge Insight CTS2 Monitor
- EGT Probe
DT LML Twin Kit: Peak Performance And Driveability
Introducing the DT LML Twin Kit for 2015-2016 Duramax trucks from Duramaxtuner.com! This kit was designed in-house with Wehrli Custom Fab to give you a product that pushes the limits of power and keeps your EGTs cool. Let's go over some of the features this product has to offer your 2015-2016 LML.
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?
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.
