Yes, you should re-map when changing to a higher flow intake. The intake combined with the higher performance slip-ons means more air and you are likely running lean. If you don't have a tuning device installed, I would pursue that then bring it to a GOOD tuner to dial it in on a dyno. If done right, you will have better performance, better mileage and you will be HAPPY. Plus, if (ahem...WHEN) you pursue additional mods down the road you are already set up to re-tune.
