I did virtually nothing to my first Rocket, which I bought with TORs and cat bypass in 2005. When Tuneboy came out, I loaded the 20050 decel tune. I tried the triple filters but the Tuneboy custom tune for that didn't work, so I took them out. My current 2007 had Jardines on it when I bought it. It wasn't running right with the 20226 tune in it so I tried a few tunes from other people, which didn't work, and I decided to get a Power Commander and have it dyno tuned. Before doing that, I put the triple filters on, mainly for the kick ass look.
