Been tossing up whether or not to get the V&H fuelpak. I've only done around 1100km on the bike and I've bought an SE air filter which I only installed to test and I found the bike didn't run that good without the fuel tuner installed, so I removed it. I've got SE street performance mufflers on the bike which made a nice difference in power once I installed them. How much more will I get if I get the fuelpak and put on the AF?

Also is it a good idea to the the V&H fuelpak if you aren't running V&H pipes?
