Has anyone ever experienced the overall performance dropping after making a small change in their tune - like idle speed? I wanted to bump up my idle speed from 850 to 900. I made the change and it worked to bring the idle speed up to 900. But then the bike started running doggy and hesitating. I reflashed the "20363Map.hex" tune back in again and it runs ok again. But idle back to 850. The "20360Map.hex" also runs doggy. Also, if I do the 12min tune or reset the adaptives, it runs doggy again. Any ideas anyone - if you are still out there?
