In March of 2008, I took my bike in for a Dyno run and a custom map after getting some performance cams installed. I was running V&H Pro Pipe at the time. I was very impressed with the performance and mileage improvements that came from a good tuner providing a custom map. Later in the season I swapped out the V&H Pro pipe for a V&H Big Shots-Long. I did not change the map with the new pipes. The performance still seemed great (no noticeable change). Is there any value in updating another dyno run to update the map for the new pipes? Thanks in advance!
