Duramax L5P Tuning Available!?... $4000!?

As any 2017 and newer Duramax owner has noticed with their truck is the lack of tuing options. Recent companies like Banks Power, Stealth, and aFe have released modules that increase the power and performance of the L5P, but really only scratch the surface of truely tuning the L5P (not trying to take away from these modules, they really do work, and are currently the best option). 

As of this week, a new break though in Duramax L5P tuning has been released through HP Tuners and PPEI, but it comes with a hefty price tag... $4000?

Here is a quote from Kory Willis, Owner and CEO of PPEI.

Lots of questions on Duramax L5P! Let’s see if I can shed a little light of things to come and as simple as possible!

1. ECU Exchange to unlock the Ecu (E41/L5P) looks to be the route these will go. Currently the price to unlock from HP Tuners is 2500. This price DOES NOT include tuning. This is simply the fee to unlock it. Yes, it is expensive, but the possibility of tuning these trucks is priceless. So determine if it is worth it for you or not. 2500 for unlock. 500 for license to tune it. 1000+ for tuning. Yes.. it’ll cost around 4K. It is expensive, but be thankful there is at least the option. As with all things - the more that comes to market... the more pricing can vary. That’s business. I’m excited and have a few ecu’s coming.

2. We can tune for ANY modifications for ANYTHING we tune. From lb7 to L5P. So yes - we can tune these for those wanting race trucks. We will also be hitting our test facility shortly to re-verify our emissions testing on this platform... so on-road tuning will be available alongside off road tuning (race tuning). Don’t abuse our right to tune race vehicles, please obey your local laws so we can continue what we love!

3. Will EZ LYNK be doing this? We do not know. Ask them.

4. Will EFILive be doing this? We also do not know. Ask them.

5. When will we be releasing? We hope to release all calibrations by the end of this month at the latest (Late September 2018). We will be doing beta testing with customers vehicles starting this week. Customers required to already have ECU unlocked. If you want to beta test and already have your Ecu unlocked or are getting it unlocked - contact us to be included in beta. Contact

This is a huge break through in L5P tuning and we hope to see it become more mainstream and hope to see the price follow and reach a much more reasonable price tag! Stay tuned with Alligator Performance and as more updates come out we will keep you informed!
