J, you will definitely NOT be blasted, especially by this guy 'cause those 2 items are all I ever planned on doing to my SRT.
Mine's a daily driver. Going for all the mods. I'd like to try isn't practical. With just a tune & a CAI (I highly recommend Needwings) you'll experience some nice gains, enough to be very noticable but not enough to be an issue with getting out on the road.
Besides, both items increase your gas mileage! You can't go wrong with an actual ROI; how many other mods. have a monetary payback?
