Very happy with the performance of my tuner on my 2011 Superglide. Also running the bassani RR 2/1 header and Kuryakin breather. Unfortunately most of my riding is not 0 - 100 sprints. I ve noticed an unhappy harmony at 50 mph in 5th, 60 mph in 6th cruising. I m tempted to adjust one or perhaps all of the enrichment dials to leaner/richer to alleviate the flat spot but I don t know if experimentation is the right choice..has anyone had a similar experience and what did you do?
