hey folks, I just purchased my predator last week and I love the power band that alot of people seam to hate, but being that I have owned numorous machines in the past I know it's only a matter of time before I feel the urge to mod. I talked to the dealer and he said that with the w/b slip on and the k&n drop in, no rejetting needs to be done unless your I believe 6 or 8 thousand ft above sea level. Is this right ? and have any of you done this and are pleased with the results? thanks
