You won't lose your warranty unless you take it in with the flies out. There really is no problem running it with the stock map and no flies it is fairly rich enough so that it won't be an issue. I rode mine that way for a couple months before I PCIII'd. But I feel your delima I felt the same way and Scavenger made me feel pretty comfortable with the idea, I did it, and no problems. But it is your peace of mind, hard to put a price or warranty on that and I got the feeling you really were hesitant simply because of the road conditions and you just plain didn't think you needed it. so sounds like you should sit on it a while.
Sorry tron got the posts mixed up it waz toyzx that didn't want to do it silly me.
It does considerably improve the low and mid power but if your not really able to use it ie. dirt roads and loose tarmac I wouldn't bother I really only ride on black top and I'm your typical what else can I squeeze out of it my bike is faster than yours wrench head so I did it. Sounds like you are more or less just riding and are comfortable with the power band as is. I would leave it (you can always do it later) on the other hand take'em out and give it a try if it's to much for your taste put them back in, it's a reversible process.
