I've never used that particular brand, but it seems decent (depending on the price.) Do you have enough mods where a aggressive tune would make a huge difference or are you stock? Personally, I wouldn't get a tuner until I had enough mods to make a huge difference. But you can mess with things like shift points, rev limiters, shift firmness, etc.
