Probably a dumb question, and I haven't seen an answer for it. It might be the wording I used when searching, but, here's the question anyway. I have a custom tune downloaded to the tuner and currently loaded on the car. I just received a new tune to try and I want to load that on the tuner. Can I download that second one on the tuner while I have my first tune currently loaded on the car? Or, do I need to revert back to stock, download the new tune on to the tuner, then load that on to the car?
Thanks!
Thanks!
