    Only the maglight mod,mounted on floor drivers side, billet antenna and have lined all storage under rear seats with rubber to keep the rattling to a minimum.
    About a year ago I added the K&N CAI and an MBRP short exhaust. I've noticed a pretty nice jump in power and of course the nice low growl. There is a point during exceleration that I feel like it lags a little from second to third. My question is, is there any "requirement" to reprogram the brain on here? If so what's the best DIY approach and what tool should I use?
