I have been looking at the SuperATV tuner for the 900. They are claiming it is dyno tuned and results in 15hp increase (they claim its even RWHP increase). With the tuner priced at only $300, it seems like a great bang for your buck! Which had me interested. I know their are other tuners out there but this one was the most budget friendly.

On their website they do not supply a dyno sheet to support their performance claim. I have exchanged several emails back and forth with a SuperAtv sales rep trying to acquire a dyno sheet. They refuse to supply the dynosheet or proof of their claims. Which I find awfully shady. I mean it is fairly standard practice to provide a dynosheet when you are selling a tuner.

Does anyone have any experience with this tuner? Or does anyone have the dynosheet supporting their claims?
