Yea, I saw that map on their site, but there wasn't one for slip ons AND eliminating the cat, which will free up the exhaust even more. Since there's multiple maps to choose from AND I now have the one that the tech guy there sent me (which I haven't opened yet), I am going to mount the carbon Mivvs with the cat intact, and see how that sounds and works first with a downloaded map, then maybe gut the cat or put in a temporary open pipe in it's place and see how that sounds and works. I'm afraid that if I gut the cat first, it may end up to loud for my girl's taste, and she'll cut me off, heh heh. It IS her bike. We shall see. I plan on taking videos of the whole shebang. Hopefully I'll end up with a better quality video than a lot of the youtube ones I've seen. BTW, 89 octane is just fine. You'd have to really modify the motor a lot to warrant 92 or up. My ZZR has 13 to 1 pistons now, and I still get away with 89.
