Hello, My name is Glyn. I have a Victory Vegas Jackpot 2006. I just recently installed an after market exhaust Bassani 2 into 1. Sounds great but it has a nasty backfire! I am wanting to complete this process with a new different air box and remap module for the injectors. I'd like to know if this would be a good stopping point for performance enhancements and could anyone recommend the specific components I'm condidering and would they compliment each other?
