From my personal experience, if interested in the ecu flash talk to the guy before you just send him your shit.
Before I found out about flashing our ECU's I got mine tuned via Dyno and a custom map installed on the Power Commander. Then when I found out about the ECU stuff, I sent mine off and told him I had the custom map on my Power commander already so there was no need to do anything to the fueling tables, he advanced the timing some and I believe they're able to make the secondary butterflies open a bit more sooner.
After that ecu flash I could tell a huge difference in how my bike ran. Speaking of which, I need to get my shit flashed again but I'm gonna remove the Power Commander this time and just get everything tuned via the ECU.
Edit: I also have the same exhaust too but w/ K&N filter. My was tuned when I had the Yoshimura cans though, I'm interested to see if there's any power gains with the Akrapovic's after a re-tune but I doubt it.
