I've been keeping track with a fuel log app on my phone. I have a little over 1,800 miles now and it's been a little better. I literally fill up every 300 miles. So far total avg since new is 27.6 but my last tank was 29.3 which included a little more highway than usual and some dyno time and fun rides with a couple people who had never been in one This last fillup now includes running Stage 1 and Eibach lowering springs, will see if anything changes.
