Our Hellcat/Demon/Trackhawk Research

OST Dyno is proud to provide custom packages and tuning for all Hellcat/Demon/Trackhawk models. Our packages have track proven times; not just dyno numbers. We have placed a lot of R&D behind these Performance Packages which means your car will perform better than it ever has before without sacrificing quality or OEM reliability.

Our Complete Packages:

We have spent a lot of time on our packages at the track making sure they perform to the best of their potential. Your car will be tuned with these same track proven parameters. Most importantly, we take care of your car while it is with us. Just like every car that comes into our shop, it will receive a complete front end wrap and any and every part will be taped off once removed. This wrap does not come off until you are on your way to pick up the car. We care about quality and customer satisfaction just as much as performance and reliability! Each package has been fine tuned with the best parts on the market. See below for a break down of each package and any add-ons we recommend. Pricing includes all labor and tuning. If you have any questions on package details, please feel free to call the shop. All prices are subject to change based on parts availability or pricing and after reviewing each car.

Our TCM Tuning:

We have been receiving quite a few calls concerning OST TCM tuning options. On our Level 2 Packages these changes have shown consistent ET gains of 1.5 – 2 tenths in the quarter mile over stock TCM programming. Details are below.
