Not much faith in the mobile dyno's. When I had my 04LE, I had it dyno'd at a bike festival that we have here on one of those mobile things. Operator said that I had 136whp. Bike had Yoshi bolt-ons and a power commander. Now, the first run said 130whp, he made some adj to the map and re-ran the bike the final run was 136whp. There was some improvement but the dyno was set up wrong.
It was free so I didn't really care one way or the other.
