Anyone used their performance packs for the 2015-2019 models? I know they just released a new one, but curious on the gains themselves even on a 2016 or 17 GT..

Was the low end torque gone with their tune? How was the throttle response? I remember when I put their CAI on my 2018, I did not have any tune, but it said none was needed, but I kinda thought the lower end torque vanished with it..

Overall, did you see a considerable difference between stock and their tune?

Have a 2019 with the PP, and being I want to keep my warranty in tact thinking of going with this power pack.
