Can't help you with anything but my opinion on the CAI. Chrysler has done a remarkable job getting an additional 10-12 hp out of the 3.6 in our Challengers. Going by memory, I believe ALL other 3.6 engine maximum HP is 295. That is because of their R&D on the air intake for the Challenger.
With 3.06 gears and the crazy low 1st in the 8-speed auto the car launches and pulls really hard up to about 40 mph. Sean’s tunes are more than just power increases, the engine runs smoother and everything just feels more refined. My mpg went up too. '22 392 Shaker 6-Speed. '17 300 S AWD.
