Have you guys tried the euro maps with the jumper mod and experienced gains over the us spec tunes? Right now I'm using the us spec tune for full yoshi along with the jumper.... I noticed the bike has alot stronger mid-range from 9k+ it's like night and day. It's been said that the jumper mod is only useful at 13K to redline...I disagree.[8)] I also turned off the fuel accelerator map and it still kicks ass...
