General Info

O2 Dynamics Ltd is the only gas engine tuning & dyno testing shop in the Rapid City, SD area. The 2wd dyno is mobile, meaning we can set up on location. Handheld tuners & custom tuning available. Some additional services we offer include carburetor tuning, dyno rental for you to do your own tuning, performance parts installations, modifying LS intake manifolds and diagnosing issues. O2 Dynamics Ltd continues to expand and learn new skills to improve our customers experiences. SCT and DiabloSport handheld tuners are usually in stock. Bully Dog tuners are available also. These have stock tunes to improve your vehicle. Custom tuning will ensure peak performance for your specific vehicle in conjunction with your driving styles and location. O2 Dynamics Ltd tries hard to be available when it is best for their customers. That means sometimes we are there at odd times and not during ‘normal business hours.’ Other times, we may just on a parts run. Remember we are small business and trying our best to please our customers. PLEASE call in advance to ensure someone is there. We look forward to working with you!
