Kory Willis, owner of Power Performance Enterprises, Inc. has proven himself as one of the most capable EFILive tuners on the market for Duramax's. He has not only proven this through his word of mouth track record, but also through holding two world records:

  • Fastest STOCK Duramax running 12.003 @ 109.76MPH
  • Fastest LMM running 10.1 @ 143MPH

Even though many know PPEI as the most capable at building horsepower, they also specialize in maximizing the efficiency and reliability of the everyday Duramax built for towing and daily driving. The platform in which we offer PPEI's tuning is via the EFILive AutoCal, and comes preloaded with your choice of a single or five custom tunes tailored for how your truck is setup and how you use your truck.

DSP5 SWITCH OPTION

We offer this package both including a single performance tuning file or with a set of five tunes. For those opting for a single tune, you will not need a switch to change power levels, but for those going with our most popular option of five tunes, you'll want the ability to change power levels. For those that would like this ability, we offer two options:

  • You can add a DSP5 Switch, which is a simple rotary knob that will allow you to toggle between the five power levels on the fly.
  • The 2001-2005 Duramax's has the ability to toggle between these power levels through the Edge Insight (similar to when using the DSP5 switch). PPEI needs to know if you plan using the Edge Insight, because it must be programmed into the AutoCal. If you do not plan on using the Edge Insight please select the DSP5 switch.

For 2006-2007 model years, the DSP5 Switch is the only method to change tunes

OPTIONAL TRANSMISSION (TCM) TUNING
For those with an automatic transmission equipped Duramax, you have the option to add PPEI's exclusive TCM (Transmission Control Module) tuning that will deliver a crisp shift pattern optimized to work in tandem with their engine tuning calibration. For people selecting TCM tuning PPEI needs the operating system number from the TCM which is not retrievable without the Autocal first. You will need to retrieve your TCM Operating system number once you receive your autocal and call us back with it to get the TCM tuning that will then be sent to your email in 1-2 business days. If you are not sure how to get your OS number, please contact us.

IMPORTANT NOTES:

  • This is a custom tuned product. In various situations, you may receive an error code when attempting to load the AutoCal onto your vehicle. In most of these situations we will need to update your stock file. If you have any issues, please contact us with error code messages available so we may promptly resolve any issues you may be having.

Hard to Beat for the Price
Size: 10 Wide, Color: Tan Leather Burnished
I purchased these for a business trip to Italy and wore them daily for the two weeks that I was there, during which I walked extensively. For me, there was a break-in period of a few days; before it loosens up, it will bite your heel, so I recommend wearing bandages or heel pads initially. Following the break-in, it's a very comfortable shoe and has served me well. I purchased a wide, and for this shoe, I found the width agreeable; in my experience, Cole Haan wide widths tend to be hit or miss (i.e., a wide is sometimes not all that wide). In terms of durability, I would not expect these to remain in good condition for more than a year if you wear them daily. The leather is not of high quality, but it's acceptable for the price. Expect them to crease very quickly if not using shoe trees. That doesn't bother me, but I know some find it objectionable. All in all, I like them and would buy them again. It's a comfortable alternative to traditional dress shoes for the office and works equally well for casual wear. Most higher quality options cost at least two or three times as much, and many are unavailable in a wide.

My favorite shoes
Size: 14 Wide, Color: White Leather
I’ve probably purchased like 40 pairs of these shoes or more. By far my favorite white sneaker. I have a large foot so the bigger sizes are appreciated. They’re versatile, literally go with anything and they are true to size. At a certain point they start to show wear and you can’t dress them up, but they last as a regular sneaker for a long time afterwards. I try to nab them on sale when they drop to $50-$70, absolute steal at that price point.

Clean Look, Super Comfortable – Instantly a Favorite
Size: 9.5, Color: White Leather
These sneakers are exactly what I was looking for—sleek, minimal, and incredibly comfortable right out of the box. The white leather looks sharp and pairs easily with everything from jeans to chinos, even dressed-down office wear. What surprised me most was the comfort. The sole is lightweight with just the right amount of cushioning, making them perfect for walking around all day. I’ve worn them on long city days and never felt sore or tired. They fit true to size (I’m a 9.5 and they’re spot on), and the quality feels premium. If you're after a versatile white sneaker that balances style and comfort, these are 100% worth it.
