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!

The History of the 5.9L Cummins

[fa icon="calendar'] Dec 16, 2019 10:08:04 AM / by Justin Tyson posted in Cummins, diesel performance

[fa icon="comment"] 0 Comments

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.

[fa icon="comment"] 0 Comments

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.  

 

Possible trouble codes

  • B2947: SHORT TO GROUND ON THE PASSLOCK SENSOR POWER CIRCUIT
  • B2948: SECURITY SENSOR SIGNAL CIRCUIT VOLTAGE HIGH
  • B2957: SECURITY SENSOR SIGNAL CIRCUIT VOLTAGE LOW
  • B2958: BCM SIGNAL INPUT VOLTAGE HIGH
  • B2960: BCM READING A VALID BUT DIFFERENT CODE VALUE THAN PREVIOUSLY LEARNED
  • B3031: BCM IS IN LEARN MODE BUT DOES NOT SEE A VALID PASSLOCK™ SENSOR CODE
  • B3033: PASSLOCK™ TAMPER
  • P1626: LOSS OF THE STATE OF HEALTH
  • P1630: THEFT DETERRENT PASSWORD LEARN MODE
  • P1631: INCORRECT PASSWORD FROM THE VTD SYSTEM
  • P1632: UNDECIDED PASSWORD SENT FROM BCM

64MM Vs. 67MM Turbo: 3 Things To Consider Before Making Your Purchase

[fa icon="calendar'] Jul 1, 2019 10:49:08 AM / by Justin Tyson posted in Turbo, Stealth

[fa icon="comment"] 0 Comments

We all get there at one point, should I upgrade my turbocharger?  It's something us diesel owners come across.  Maybe your charger blew up or maybe you just want to help cool your truck's EGTs a bit more.  There are a ton of different reasons why we want to upgrade.  With that comes a ton of different variables that go into which turbo you SHOULD buy.  Let's take a look at three big things to consider. 

VVT Stealth 64-1

#1: How Do You Use Your Truck?

You've heard this one before, if you're new to the diesel world maybe you have not.  How do you use your truck?  Do you commute 20 miles to work and back daily?  Do you haul any toys?  Maybe you hotshot as a career, all these are some of the ways a driver uses his diesel truck.  A driver that tows a lot would best be suited for the Stealth 64, why?  It runs more efficiently at higher horsepower numbers while loaded.  The truck will sustain a heavy load for longer because the heat that the turbo is introducing is lower than a stock charger.  Lower piston temps, lower EGTs equals more time and a larger buffer before the truck is affected by the added heat.

COST PER HORSEPOWER

[fa icon="calendar'] Apr 23, 2019 10:00:00 AM / by Paul Wilson posted in what are some upgrades I can go to my LML?, Duramax Turbo, diesel performance

What is "Cost Per Horsepower"?

Cost Per Horsepower is a simple way to display and measure the cost-effectiveness of automotive performance upgrades.

In practice, this term is probably more often used to prove someone has wasted money on a specific upgrade or the purchase of an entire vehicle.  For the purpose of this article, we are going to assume the vehicle in question is either a Duramax, Cummins, or Power Stroke diesel truck.

Benefits Of Tuning Your Ag Equipment

[fa icon="calendar'] Apr 11, 2019 11:44:46 AM / by Justin Tyson posted in tractor tuner, tractor tuning, tractor, Tuner for tractor, Agriculture, power manager

There is a more cost-effective way of pushing your tractor to the top of the line when it comes to power.

You want field time decreased and you want to use the least amount of fuel possible while in the field.  These two aspects save you two valuable items: time and money. You work hard trying to get the best yield out of your land, so why not expect your combine to do the same for you?  Tuning your equipment is the quickest, cheapest, and most efficient way of going about getting the most out of your tractor. It can up-rate your tractor for a fraction of the dealer price and bring you the top-end amount of MPH and power.  Let’s go ahead and examine what tuning can do for the equipment.
