Agreed, jmgak47 is a great source. I will be buying my custom tune from him soon.You would be best off to grab a super chips for any direction you decide to go. If you want a cookie cut cam like lonestar said sidewinder or the comp 260 will run on a can tune. If you are looking to get even more out of it try and get in contact with jmgak47. He is a quite knowledgable guy on this matter and just spec'd a cam out for a guy also running an 03 that was quite a bit bigger than a 260 but would still run on a super chips tune.
