The numbers are in… 🏆 And We Have A WINNER! 🏆

🔥 The 2024 L5P put down 750HP on the dyno! 🔥

That’s our ALL NEW E42 stock fuel, drop-in turbo horsepower record! 🏆

Making the winner’s for our guessing game and the $250…
🎉Evan Deher🎉 & 🎉Erick Macias 🎉

So, what made this possible? This 2024+ E42 L5P was running:

• Stock HP4
• Stock injectors
• Stealth 67mm Mach 2 turbo
• WC Fab piping kit
• New SRF intake horn
• AITP Max Effort tune
• AITP TCM tune

A huge shoutout to for bringing us his 2024+ L5P and trusting us to put our favorite 24+ drop-in turbo setup to the test. 🤝

And another big shoutout to Luke Luke Nelson for sending us his newest creation, the SRF intake horn. 🙌

The reason for this testing was to see exactly what we could gain by moving away from the factory intake horn.

Here are the final results:
716 HP w/ Stock Horn, 742 HP w/ WC Fab Intake Horn, and 750 HP w/ SRF Intake Horn

That’s a 34 HP gain over the factory horn. 👀

We might never get tired of looking at this truck… ✨🛻✨👀

And with what we have cooking behind the scenes, we don’t think you will either.

With the latest E41 updates, including our permanent dash message fix and all new SMC tuning, the E41 platform is now fully supported through both HP Tuners and EZ Lynk.

While Aron has the marketing team staying busy, development for some even bigger and better things is already underway behind the scenes…

Let’s just say you might want to make sure you’ve got the follow button clicked… 🛻💨👀🔥

📈‼️ MORE “INFLATED” DYNO NUMBERS from your favorite L5P Tuner’s in the industry! 😂

Another AITP tuned L5P putting down numbers that are apparently wayyy too good to be true…

This 2021 belonging to Tucker Mathias is making some serious power with:

💥 AITP Tuning📈
💥 Dan's Diesel Performance INC 100% Over Injectors
💥 Dan's Diesel Performance INC 12MM CP3
💥 Dan's Diesel Performance INC 66mm Drop-In Turbo

The haters are going to say this truck did not make 840HP...

But multiple trucks making over 800hp on multiple dynos is not just “marketing”. It’s a combination of quality parts and tuning. Many folks may not understand that.

🎛️📈SMC Tuning is now available for existing 2018-2023 L5P EZ Lynk Customers. 🙌 

If you’ve previously purchased 2017–2023 L5P Duramax tuning from All In Truck Performance through the EZ Lynk platform, you now have the option to upgrade to our new SMC (Switchable Map Control) tuning.

The new SMC file can be found and installed through the ECU Profiles section of the EZ Lynk app. Once installed, you can check the function of and change the switchable Power Maps by following these steps:

1. Turn cruise control off.
2. Hold the cancel cruise control button for a few seconds.
3. The cruise control indicator will appear with a number next to it.
- This number indicates your current Power Map.
4. Use the + and – buttons on your Tap Shifter to move between Power Maps.

If you already have our 2017–2023 L5P EZ Lynk tuning, check your ECU Profiles the next time your EZ Lynk device is connected to your vehicle to see if the SMC upgrade is available.

If you have any questions about the upgrade, installing the SMC file, or using the Power Map switching function, feel free to reach out to the All In Truck Performance team. We’re happy to help.

We’ve been working hard behind the scenes on some new products and releases. But some things just can’t be put off, and getting out to Dallas for my wife’s surgery this week is one of them.

Behind the trucks, the dyno numbers, the tuning, and everything we’re building here at AITP are real people, real families, real responsibilities, and people we’ve been entrusted to take care of.

We brought Deborah along for the trip, and it’s hard not to appreciate just how far this truck has come while thinking about what actually matters most:

• Exergy 200% Injectors.
• Exergy 12mm CP3.
• Forced Inductions S491 over:
• Stealth 67mm Mach 2.
• DHD-built 10L1000 transmission.
• 1,040 HP

There’s always another truck to build, another product to release, or number to chase. But sometimes you have to take a step back and take care of the people God has put in your life.

Here are two AITP tuned truck owners that sent us feedback recently.

Jared Cocanougher and his dually L5P nearly took the sled back to the pits with him, putting down one hell of a pull and dragging it nearly off of the track.

And Josh Bormann backed it up with a more than respectable 1st place finish out of a 40 truck line up after putting down another full-track pull in Iowa! 🏆

It’s awesome to see what our tuning can achieve, but even more rewarding to see our customers enjoying their trucks to the fullest potential. Huge congratulations to Jared and Josh! We’re very proud to have you guys representing AITP. 💪🔥

Harry’s recovery is officially underway, and he’s already eyeing his next dyno competition. 👀

While his new rotating assembly is out getting balanced at the machine shop Debora decided to swing by and pay him a visit. With a goal to hit the dyno again soon, he’s going to need all of the support he can get! 

If you’re rooting for Harry, help us push him towards the finish line by liking, sharing, and following along as we continue to share the tear down and build. Every bit of support will help!

Harry has officially touched back down at AITP! 🇺🇸

First and foremost, a huge thank you to Michael Carrasco for getting Harry out to Kentucky and safely back home from Boosted Blackout this weekend. Getting a truck like Harry to an event like this is no small task, and we really appreciate you making it happen!

And of course, we can’t forget everyone else who played a part in making this such a truly great event.

Big thank you to Stack’d Diesel Specialists for hosting Boosted Blackout and putting together an event that brought so many great people, trucks, and businesses together. We are very proud to be a part of it.

Huge shout out to Luke's Diesel Repair LLC for sponsoring the event and asking us to come out. We so much appreciate you supporting diesel events like this and we wouldn’t have been there without you.

Clay and the entire CAM Performance LLC crew definitely deserve a a lot of credit too. They did an incredible job running the dyno and putting together one hell of a test. That was easily the most intense dyno pull we’ve ever made. It took nearly 1,000 horsepower just to pull through the load with the way the test was set up. We couldn’t have asked for a better crew to put Harry through his paces.

And finally, David Letcher thank you for putting together an awesome edit of Harry’s time both on and off the dyno.

This weekend wouldn’t have been nearly as memorable without every one of you. So thank you to everyone who put in the time, work, and effort to make Boosted Blackout what it was.

We had an absolute blast and are definitely looking forward to the next one! 🤘
