Derks Custom CARS, Biggar
We are a small Custom Shop in Canada, we have been tuning gas and diesel engines since 2008. All our tunes sold on this page have been tested locally with good results. We do a lot of custom work, mostly LS swaps, Duramax swaps and pretty much anything else you can think of. We can program just about any GM ECM, PCM or TCM on the bench, no vehicle needed. As for Chrysler and Ford, we can program the most common ones. Of course all of them can be done while in the vehicle, If what you are looking for is not listed here, get in touch! More products and updates to follow! We are open to any suggestions, please contact us if there is any suggestions you might have!
