Re: My 04 Yamaha R1
Again, thanks for the comments everyone 
There aren't many advantages to the YEC ECU, the only parts I could take advantage of are the timing adjustments and secondary butterfly restrictions. With those changes I'd be really lucky to pull in another 5hp.
As it sits now I've already hit 187mph and 186mph via GPS (I still need to snap a picture of the GPS) which is highest I've seen for a street R1 (most folks will say they've hit 189mph(the speedo limit) via the speedo, a few of us have rode till it read 189 then glanced at the GPS which is usually reading in the low 170s).
