DSX Tuning GM LS/LT performance parts, Huracan/R8 5.2L V10 performance, and Volkswagen/Audi/Lamborghini service.

DSX Tuning is a GM parts manufacturer focused on total integration on parts. From precise fitment based on GM data to innovative and robust electronic interfacing, we ensure the products function the way they need to without the boundaries of off the shelf parts. We are also a Volkswagen/Audi/Lamborghini service center providing support with APR, 034, IE, Unitronic, and DS1 as well as developing parts and solutions for the 5.2L V10 platform, including our own in house manufactured billet intake manifold.

This has been a long time project I wanted to pursue that I only had the confidence to take on recently. We’re excited to add this into our ecosystem!

What is it? Real time tuning for E92!

Are you wondering why you get a XDF when we patch your Atlas file? This outlines why! We continue to add features for the Atlas eco system, and we’re excited to bring you more.

Working on some new stuff… which involved turning a lot of this 80lb blank into chips in one of our UMC750SS machines.

Any guesses what this is for?

Wanna see what your car is doing? We’re finalizing this piece which coincidentally will also have some input functions to the ECM!

As we install a Magnuson Superchargers 2650 on this 2025 CT5-V Blackwing, we noticed the coils are different compared to the pre-2025 which means the supplied relocation bracket from Magnuson does not fit because the coil cannot clock properly.

Luckily, we have in-house 3-axis and 5-axis capability, so we built a program that clearances all the needed areas to allow proper installation. Bandsaws and grinders shouldn’t be part of the repertoire here, and we think this turned out about as nice as can be.

Do you need your covers clearanced for a 2650? We offer this as a send in service for $250!

The latest Atlas update is now available on the site! Aside from some housekeeping, the big change here is the addition of station mode for the wireless connectivity and adding boost control editing to the main UI (just the enable selection). On the FCU side, there's the addition of editable closed loop re-enable delay as well as some updates for the upcoming Advanced Power Management operating system for the E92.

Pic for attention. 😆

We learn, we iterate, and we turn that into something useful for you. This is something I set out to do months ago, and we’re finally happy with how it behaves. Traction control for the factory E92 was at the heart of this project, and it required learning a lot of techniques along with really digesting what the factory code is doing.

It’ll be a bit before we can get this out as it’s a significant amount of code to inject and iterate across operating systems, but we’re also looking to take steps to protect it from copying at the same time. We swear… this won’t be vaporware. 😂

This is the next evolution of the E92 patch for Atlas. This will all be available in E90/E99 as well.

This was something on the to do list for a while… better late than never, right?

The next UI update will allow you to connect your Atlas to your home or shop network, and then any time you enable the WiFi, it can be set to automatically connect. From there, you just type the IP address assigned into the browser bar, and you can do everything you normally would. The benefit of this is a tuner can remotely log into your computer and do whatever they need to if they want to set your Atlas up for you. All you need to do is the physical enable of the network!

For a NA car that made ~535whp bone stock, I’d say this is markedly impressive for one single modification that won’t require swapping tunes and test tubes. 👀👀
